Inertia X Frame

Description

The multiple award winning Klymit Inertia X-Frame is the world's lightest, most compact, and most advanced full length camping pad available. Designed with body mapping research, it gives you support and comfort in all the key pressure zones, while eliminating unnecessary material to reduce weight and pack size.

Ideal for 3 season use, the Inertia X Frame rolls up to the size of a Coke can, and takes only a few breaths to inflate. However, it still offers the adjustable comfort through the use of a dry air pump, which allows you to reach higher pressures than ordinary mouth-inflatable pads. The cut-out regions of the pad not only reduce the pad's bulk and weight, but are the basis for the patent pending Loft Pocket Technology. Whether you place your pad underneath or inside of your sleeping bag, Loft Pockets allow the insulation on the bottom of sleeping bags to maintain loft and warmth beneath your body, where it would normally be compacted and useless. Loft Pockets also promote breathability. Simply put, you can always sleep in any condition to which the sleeping bag is rated on any of our camping pads with Loft Pocket Technology. Built with ripstop 30d top and coated 75d bottom, the Inertia X Frame is also one of the toughest pads on the market.

Love the X Frame Review by Tom Conly
It was my first trip in the bush with the x-frame and it performed very well. The overnight low one Friday night was -15C (5F) but I was toasty warm. I used the pad inside of my Mountain Hardwear ghost bag with a thin pad underneath. I couldn't feel any cold coming up through the ground. It did seem to let the bag loft on the bottom. I was very pleased with how comfy and warm the pad was even in the cold. And I've never had such a light pad setup in the winter. I slept on the pad in a cotton canvas tent the first night and under a tarp in a bivy the next night. (Posted on 4/11/14)
IXF Is Great! Review by Michael Gonzales
When I get new gear, I try it out in my backyard before hitting the trail. Love the Klymit Inertia X frame and I will be passing it along to my backpacking buddies. The Klymit Cush pillow/seat is a hit with me. The ingenious design for height adjustment and the ear well is a awesome. I will also be passing it along to my backpacking buddies. The addition of the Klymit Inertia X frame and the Klymit Cush pillow/seat has lowered by base weight to 7.5 lbs. (Posted on 4/11/14)

Throwing down with the X Frame Review by UpaDowna
Throwing down hard with the industry's lightest weight new sleeping pad design, Klymit has no doubt firmly placed itself as a company that is not holding back when it comes to possibly re-inventing the wheel er, ah, the sleeping pad.

I want to be clear straight away that this pad is the answer to an ultra-lighter's dilemma when it comes to whether or not sacrificing comfort is worth a few extra ounces. Most fanatics will go to such extremes as filing down their gear and removing extra padding or straps from their packs, they push to carry less weight for a number of reasons, but regardless of what drives the individual it is important to know that Klymit has taken notice and worked hard to develop a means to insulate a person from the ground as well as comfort their slumbers. lacking.

At first glance I thought "what in the heck is this thing" and "it must be another hair brained idea made by lab rats with no real world camping experience". Well I couldn't have been more wrong.

When I laid down on this mat I was actually amazed that it was padded right where I needed it. Sure there will be some folks that it just doesn't feel right especially due to the varying lengths and individual phenotypes of people. But to be honest I think they should bill this as a "one size fits most". If you really think about who the market for this thing is, the ultralight fast packers, it is a godsend insofar as now there is a viable sleeping pad that weighs virtually nothing and allows so much more comfort than most are used to. What is more than that is as folks try it I am sure they will become converts as well, it is too light weight and too practical to ignore.

One of the lesser appreciated features with this pad is that the phrase "less is more" actually applies, you see all of those cut out areas actually allow your sleeping bag to keep it's loft. After all loft is why your bag is able to keep you warm in the first place. Compressed insulation is worthless, but fully lofted insulation has optimal heat retention properties. Aside from the amazing and well thought out channels the Klymit folks decided to provide 2 methods for filling the X Frame, the first is the usual air mat method of blowing into it (took me 3 full breaths) or with an included hand pump which allows you to fill the mat fuller than through lung power alone. And with the highest burst rating of any mat at a full 10psi I have no doubt you can get this thing to support you well enough for it to not be a concern. The Inertia X Frame packs down to the size of a beer can (12oz not the big 24oz ones). Which in turn will no doubt free up some cargo space so you can, well, carry more beer!

So regardless of if you cut off your toothbrush handles or you bring a cast iron dutch oven on your trips, this product is one that you need to take the time out to consider. Bigger folks may want to give it a go in the store first so you know if you are going to hang off of the side. Yes it might take some time to get over the psychological impact of "less is more" but the folks at Klymit did their research. For the record I slept on it on my side, back, and belly and it performed a lot better than my preconceived notions. I can't wait to see what else Klymit has coming out for us in the coming months.

I was utterly astounded by the effectiveness of this sleeping pad. Review by Will
I was utterly astounded by the effectiveness of this sleeping pad. Two broken clavicles, one broken shoulder, and three knee surgeries have turned me into a rather discerning backcountry sleeper, and the X-Frame’s Spartan construct concerned me immensely. Fortunately, my worries were unwarranted. The 1.5” thick pad has cushion in all of the right places thanks to ‘body-mapping’ technology...As a bonus, it’s also easy to inflate (it took me four or five good breaths) and quick to deflate, too.... Amazingly, I was just as warm and comfortable in my 20 degree bag as any other night of backcountry sleeping, and the cushion was so effective that I could even sleep on my side....Bottom Line: The X-Frame is an excellent choice for the fast and light, three-season crowd who are still looking for a little bit of cushion at the end of their day.

Beyond Comfortable Review by N Scales
I have spent a lifetime sleeping in the dirt, it's something I'm proud of. My new Klymit pad changes everything. The pad is beyond comfortable, packs up tiny small, and even seems to make my sleeping bag warmer. Thanks for making a great product. (Posted on 12/2/-1)
Actually Works Review by N. Greece
When I first saw the box that my Klymit pad came in I was pretty skeptical. How could something so small provide any level of real comfort? I still actually can't believe it works- and it doesn't just work, it's phenomenally comfortable, AND it helps keep me warm! Thank you Klymit for creating such a lightweight, insanely tiny pad that more than does the job! (Posted on 12/2/-1)
Paragliding Pad Review by M. Beechinor
I've spend a lot of nights every year under the stars with a minimal amount of gear, but that doesn't mean I don't like to be comfortable. For paragliding expeditions though, we aim to fly alpinist style, ie with the least amount of gear possible. Thermarests have always been too bulky and too heavy to even consider so I've always just slept on my wing, which is far from ideal. Now I've got a proper pad that weighs next to nothing. Thank you! (Posted on 12/2/-1)
Radically Improved Comfort Review by G. McClurg
For bivvy paragliding our survival gear has to fit in the space of a small book bag, as we have limited space in our flying harnesses. Lighter, headlamp, food, water, lightweight sleeping bag, small pot and a small first aid kit. I've never considered it possible to also be able to bring a sleeping pad as we just don't have the room, or the space. Klymit's XFrame has radically improved our comfort in seriously challenging environments. (Posted on 12/2/-1)
Motorcycle camping trip Review by Frances
I purchased this item for my first motorcycle camping trip. I looked at several other brands but was impressed by the small size of the Klymit brand. It packs up really, really small which was a big plus for me.

We camped for 8 days and it held up very well. It never lost any air at all. I'm 6'4" and weigh about 185 lbs. and the mattress seemed to provide ample enough support for my body. The only problem was that after sleeping on it for several hours, the small of my back would begin to hurt. I tried the mattress in different positions and with different levels of air in it, but nothing seemed to solve the problem. i wound up sleeping on my sides much more that I would like. I couldn't figure out why this happens. (Posted on 12/2/-1)
Ridiculously Small Review by Genaro
I really had my doubts that this thing would actually provide the support I need, especially after pulling it out of the shipping package. It's tiny. Really tiny. It's tiny even compared other very light pads. As a comparison, you could fit maybe 4 or 5 of these in the space taken by a Thermarest Trail Scout. Ridiculously small.

So, until I tried it, I thought "there's absolutely no way this will give me a good night's sleep...". I was really surprised. The body mapping does work, and I get a full night's sleep without any soreness. I find that I adjust a couple times a night to stay positioned on it, but the same thing happens with a regular pad too, as I slide around (I'm a very active sleeper). It fits nicely _inside_ all my bags, which helps to keep it in place.

It's also cheaper than any other comparable ultralight pad.

Be aware that this model is designed for ultralight enthusiasts. It goes in my daily travel bag, which I keep super light. For general camping use, or longer stays, I prefer the larger XL model. It's extraordinarily comfortable, and still lighter and less expensive then the competitors. In my experience, that model is the best all around pad on the market, and perfect for the widest range of average users. If you're choosing between this pad and the bigger Klymit model, and have any concerns about comfort, go with the XL. In a large pack, the few extra ounces are definitely worth the amazing comfort the XL provides.

I'm a complete convert to Klymit - never going back to any other brand. All their models earn five stars from me, without reservation. (Posted on 12/2/-1)
Not for car camping Review by Ernie
If you need to save weight on your back and space in your pack then this mattress is for you. This is great for ultralight backpacking. I can also fit the Klymit Cush pillow in the stuff sac and together they weigh about the same as a can of soda and are about the same size. A great combo for hiking. Now I only give this item 5 stars as an ultrlight mattress. If you don't care about weight or size this one is not for you. It works best if you sleep on your back and is narrow. You can sleep on your side and it still feels ok. I have not used it in cold temps but it is not rated for winter. If you need a bigger mattress or plan to sleep on big rocks, get something else. This is great for ultralight use but for car camping it is a waste of money. And yes, I am buying more X Frames for my family to hike with and Therma rests to car camp or winter/short hikes with.

In love with this Mat Review by Armando
I spotted this mat at a local camping store here in Australia. At first I was confused to its function; it looks like a something you take to Everest to stop you rolling down the side of the mountain. I checked the price and quickly dismissed it as it was outside of what I was willing to spend.
After spending a good two hours trialling sleeping mats, I gave up and went home...

Now I am thankful I did. After watching many videos and reading review after review, I pulled the trigger.

Wow, what a mat! It really is as small as everyone says (the box that arrived at my door felt empty).

I spent 4 nights on this mat and actually looked forward to sleeping. My camping buddy aptly named it the 'spinal board'. It inflates with roughly 4 breaths and is ready to use. Depending on how firm you like your mat, you may find that 2-3 breaths are enough. The hand pump bulb thingy lets you really crank up the firmness.

I found the mat to be super comfortable. The first night I tried it inside my bag, and it seemed to work ok. I move about in my sleep and did find that it could get a little tangled. On the second night, I put it under my sleeping bag and much preferred this arrangement.
If you are a side sleeper, you may want to pump it up a little firmer. I had the mat mouth inflated and ended up dropping the pressure a touch with the release valve. I still found this supportive on my side (although I rarely sleep like this). For the front sleepers, this mat has a little party trick. When lying face down, it seems to lock your legs in so they won't fall over the sides. Your legs will have more freedom when on your back, and I actually preferred them over the edges. Either way, you will find what works best for you.

Never did I feel that this mat was inadequate for car camping. I'm aiming to take it away hiking soon and still believe this product is the perfect balance of size and comfort.

If there were any negatives, it would have to be the material. The top is 30D while the bottom is 75D. Most camping mats in this price range feature a 75D top and 150D bottom. I'm sure this is a physical limitation, as a denser material would probably not fold as easily, but I am a little concerned about the long term durability. That being said, my tent was sitting on many little rocks and twigs and the mat is still going strong. Plus, a generous patch kit with a substantial amount of material and glue is included.

I'm in love with this mat. Having the ability to store it inside a pack is a big plus in my eyes. My last mat was ruptured on the bus ride to our starting point. It was strapped to the outside of my pack. Go figure. (Posted on 12/2/-1)

One of my favorite pieces of equpment. Review by Eli
I am 5'2 small lady that loves to backpack 1 - 2 time a month. This is one on my favorite pieces of equipment. Super lightweight, easy to pack and slept well. This worked well with my down sleeping bag. Now getting one for my boy. (Posted on 12/2/-1)
Don't need the pump. Review by Adan
I was skeptical but this thing works pretty well. I'm not going to say it is every bit as comfortable as a full size pad because I've not used a good full size pad but this does do the the trick. I couldn't see giving up the pack space for a larger pad and hated the idea of a half pad. This packs down to Cola can size with no effort. I don't use the pump, leave it at home. Blows up in five breaths. I've even had to let a little air out after blowing it up by mouth. Been told that causes mildew and shortens the life of the pad but I'm pretty sure it would take some work to blow this up with just the hand pump though I haven't tried. So if you're of that school you'll need to have another option for inflation. (Posted on 12/2/-1)

Convenient to setup Review by Roman
I would suggest putting this inside your sleeping bag to ensure that you never fall off. This is the first inflating sleeping pad I have ever used. I had a good experience. We did a short trek in Philmont Scout Ranch and this pad lived to tell the tale. It was comfortable and it fit my frame. It was extremely lightweight and convenient to set-up. (Posted on 12/2/-1)
Take it with me when I camp or travel Review by Allan
I love this sleeping pad. I first used it in Joshua Tree in the spring with lows in the 50s and slept on the ground with my sleeping bag on top of me. I was warm and comfortable. I mostly sleep on my side and the X-frame was very comfy. I read some reviews that side sleepers did not like it. I doubted it would work for a side sleeper. I was wrong, its great.

The second time I used it was with my Hennessy Hammock. The lows were in the 50s and there was strong winds. Even in high 60s your body next to the hammock will chill. The x-frame worked great keeping my away from the hammock. I found just a sleeping bag over me and the x-frame between me and the hammock keep me warm. It also fits well in the hammock and stayed in place.

I will take this with me when ever I camp or even travel. I am not worried about any long airport delays now with this in my carry on. Ill just inflate and camp out at the airline gate. (Posted on 12/2/-1)
Light and very packable Review by Omar
I got this as a gift, so I have no financial attachment to it. It works great. It's VERY comfortable, surprising by the way it looks. I sleep on my back, side, and stomach sometimes and all 3 work good with this pad. Believe it or not, I find side-sleeping is the most comfortable on this thing. I'm shorter 5'6" so I had to scoot a little for my best fit, but I also use an additional pillow and wasn't worried about my head. I first tried it with my feet off of the pad, but it felt really weird having my feet at a lower level than the rest of my body, so using the footrest at the bottom felt much better. I roll this up with my sleeping bags and keep it in the stuff sack. Light and very packable. I have not slept with it inside my sleeping bag and don't plan to. But under the bag works great. I do notice it slips a little bit on the ground, however, my bag and body go with it, so I don't even notice it while I'm sleeping. But when I get up in the mornings, it's in a little different location. I use the product for backpacking, camping, and sleeping over at other people's homes on the floor when needed. Inflates very easily(I don't use the pump). The only thing I don't know is how durable it will be. So far, so good though. I do notice sometimes if you're sleeping on your side and your body pinches your shoulder against one of the tubes rather than the whole pad surface area, you'll wake up with your arm asleep, I have had that happen a couple of times and just readjust. (Posted on 12/2/-1)
Great for side sleeping Review by Casey
There are plenty of reviews on this product so I ill keep it short. I am used to the more bulky foam pad. I live in Texas so I haven't used it to keep me warm yet. However, it was great for side sleeping and almost just as good for when I lay on my back. Best pluses are the light weight, compact size, and easy inflation process. (Posted on 12/2/-1)
Right amount of comfort Review by Franklyn
Bottom line, it offers just the right amount of comfort with ultra light, ultra compact, ultra ease of use. I do agree with an earlier reviewer who suggested having an alternate size for a smaller (ie. women's) bag. It does fit a bit too snuggly inside my bag (which is not a women's bag even) to the point that I would not be able to tighten/close the hood as much, if needed.

I marked that I'm comfort driven for gear style, but am very weight driven as well. I'll pay up for less weight, but have been known to carry extra weight for comfort. Thus I was so excited to see this sleeping pad that offered both comfort and ultra lighweight. NeoAir is known for lightweight and comfort, but it just wasn't all that comfortable to me. Possibly because I'm more of a back sleeper. I also didn't like how much effort the NeoAir took to blow up and take down. This pad is extremely easy to do both. In fact, I just leave it inside the sleeping bag and the sleeping bag inside the tent, stuffing all into bottom of my pack, making the whole take down and set up a cinch and efficient in a number of ways including use of space in the pack. Specific to comfort, I still toss and turn as much as I do with any other pad, inluding my luxurious large (25 inch wide, 1.5inch thick) ThermaRest Prolite Plus. So, I consider it comfortable as one can get not being in a bed. My first use was during a week long trip in Ansel Adams Wilderness. I didn't take the pump. It was comfortable enough, but was kind of missing the thermarest...but not enough to take the weight back. I have since used the X-Frame with the extra firmness using the pump and found that did the trick - now just as comfortable as the luxurious thermarest prolite. Well, I guess the termarest at 25inch wide, it gave more space for that toss/turn...but not worth the almost 2 pounds anymore! Further speaking to comfort, on that first trip with the X-frame I went without the pump/extra firmness and was able to sleep on granite rock. (Posted on 12/2/-1)
Good job Klymit! Review by Horacio
This pad is probably the best pad I've ever used! I move around a lot at night and it stays with me (6'1" and 165lbs). I feel like this pad is specifically made for people my height. I throw it inside my sleeping bag(Phantom +32) and its surprisingly very warm. 30 degrees and up. This product does what is says. I would recommend using this only for 3 season by itself. Thanks for the great product which I'm sure ill use for many seasons! Good Job Klymit! (Posted on 12/2/-1)
Great Review by Sherman
I couldn't believe that this sleeping pad was real when I first saw it. All the other reviews are right, though; this is a surprisingly comfortable pad, and for the size/price combo, I don't know if anything else beats it in the lightweight/minimalist category. I'm 6'1", so I was a little worried that I would be too tall for the padding zones, but that wasn't a problem at all. If possible, I would recommend trying the pad out before buying it to ensure that it's compatible with your body type and sleeping style, but for a tall side-sleeper like me, it's great.

It Works Review by Alexis
IT WORKS! Ive owned multiple types of sleeping pads and they were comperable with one exception, side and wight. I weigt 255 and Im 6'1. This pad is a great example of thinking outside the box. I was in Colorado for 7 days and temps got down to 35 deg or so and all I know is when dressed appropriatly I was comportable. I used this mat in my bag and outside the bag and it was fine. I am able to find my center more easily with this mat because of the frame work design. There was not a tendancy to get pushed to the side.

The size and weight is perfect and I could just roll the pad in my sleeping bag.I slept on the ground and had no issues leaking or anything. For my comfort I dont even have to use the pump. I just blew in it till it was full.

Great job Klymit. (Posted on 12/2/-1)
Great for me Review by Susan
I bought this pad to reduce the bulk I carried on my summer trip to Norway. I was expecting it to perform well, but I had no idea how much more comfortable it would be than my women's Therm-a-rest pro lite plus.

My first trial of the X-frame was backpacking in Rondane National Park, Norway, before the summer tourist season picked up. Conditions were wet, snowy, and much colder than we had anticipated, with daytime temps as low as 41F. We pitched camp on uneven ground in a three season family style tent that we picked up locally. My sleeping bag is a 15 degree Marmot down women's bag.

My old Therm-a-rest shifts under me a lot, so I set up the X-frame inside my bag the first night to see if it made a difference. The gray side of the X-frame is slip-proof, adhering to fabrics like longjohns quite well, so make sure it goes downward if you've got the X-frame inside your bag. The green side is smooth and comfortable against the skin.

Setting up the X-Frame is a snap. It takes me closer to six or seven breaths (not the advertised four) to fill it, and then I use the included hand pump to give it more firmness than I can manage with lungs alone. The pump is small enough to fit in the palm of your hand, and can be rolled up with the X frame to store it easily in the included stuff sack. You could shave off an ounce by leaving it at home, but for me the added firmness is well worth the weight.

After my first twenty minutes in the X-frame, my shoulders and hips were toasty warm, but my ribs, thighs, and feet were freezing. I had stuffed the X-frame into my bag any old how, and my weight on the pad had compressed the sleeping bag under the vents in the X-frame. The fix was to pluck up the sleeping bag through the holes in the X Frame to give the bag's insulation more room to loft. Thanks to the grippy gray side of the mat, I only had to do this once at the beginning of the night and the bag stayed lofted despite a night's worth of shifting around from back sleeping to side sleeping -- both of which are very comfortable in the X frame. An added bonus for side sleepers is that the vents give your arm a little more room under you so you don't feel like you're dislocating your shoulder in your sleep.

In Norwegian parks, you camp wherever you find ground that's mostly flat, and at Rondane, that puts you on top of a party mix of exposed rocks, heather, and lichen. Back home in my thermarest, I would shift around all night trying to shift my hips, knees, and shoulders off the stones and roots under the mat, so it came as a surprise on day 2 when I discovered that I'd slept on a boulder the size of a soup plate. The X Frame just molded around the rock so I never even knew it was there.

I made coffee and breakfast sitting or kneeling on the X-frame the same as I would on my Therm-a-rest without any discomfort.

Packing up again is easy. I just opened the valve (almost all the air escapes instantly) and then stuffed my sleeping bag, X-frame -- pump, and all -- into my stuff sack.

My only recommendation for the company would be to make a version of the X-frame sized for women's sleeping bags. In my women's bag, the X-frame extends from the end of my toe box to the tip of my hood, and it's wide enough that the bag is stretched pretty flat across the hips when I'm inside the bag. The large size of the X-frame compared to a women's bag makes it hard to cinch the hood around your face and reduces insulation in the toe box. My feet warmed up eventually, but I think it would have gone faster if the the bag hadn't been pulled taught.

For couples: I zipped my bag up to my husband's on the second night in Rondane with my X-frame in my bag, not under it. My husband is retro and had brought a basic foam roll-up pad that was under his side of the bag. The X-frame was so comfortable configured this way that I forgot I was sleeping on it, up until it shifted away from his mat in the night. The cold coming up from the zipper area woke me up, but it was no problem to just scooch the X-frame back so it overlapped my husband's mat. In my old Therm-a-rest, I couldn't zip up to my husband because it would shift out from under me in my sleep and I'd freeze with no good way of adjusting it back. The next morning my retro-loving husband considered getting an X-frame, which is praise indeed.

You won't miss the bits of sleeping pad that aren't there, you will appreciate the tiny form factor when packed, and will marvel at the lofty warm cushioning when inflated. (Posted on 12/2/-1)
Works Surprisingly well Review by Jens

Skeptical at first Review by Jon
I received this as a gift from my wife and was admittedly skeptical of the comfort of this pad. After 2 weekends in the Tetons I can say I am blown away. It does everything a camping pad is supposed to, but better. It is very comfortable for me as a side sleeper, is the lightest and most compact pad I have ever seen, and seems pretty bomber compared to other inflatable pads I have used. I was most surprised by the warmth. I know exactly how cold I can take this pad because the warmth is based on the temperature rating of my bag. 18 degrees was toasty on this thing in my SD Nitro 15. I'm not so sure it would work at -50 in a -50 bag though...but at normal winter temps I think it will be fine. Bottom line for me is that I really sleep well on this pad, and it saves me a ton of weight. (Posted on 12/2/-1)

It isn't too often you see a genuine innovation in something like a sleeping pad. This baby is sweet, it is lighter, smaller and more durable than my old Neo air.

Really Surprised Review by Nick A
I was really surprised. The body mapping does work, and I get a full night's sleep without any soreness.
I really had my doubts that this thing would actually provide the support I need, especially after pulling it out of the shipping package. It's tiny. Really tiny. It's tiny even compared other very light pads. As a comparison, you could fit maybe 4 or 5 of these in the space taken by a Thermarest Trail Scout. Ridiculously small.

So, until I tried it, I thought "there's absolutely no way this will give me a good night's sleep...". I was really surprised. The body mapping does work, and I get a full night's sleep without any soreness. I find that I adjust a couple times a night to stay positioned on it, but the same thing happens with a regular pad too, as I slide around (I'm a very active sleeper). It fits nicely _inside_ all my bags, which helps to keep it in place.

It's also cheaper than any other comparable ultralight pad.

Be aware that this model is designed for ultralight enthusiasts. It goes in my daily travel bag, which I keep super light. For general camping use, or longer stays, I prefer the larger XL model. It's extraordinarily comfortable, and still lighter and less expensive then the competitors. In my experience, that model is the best all around pad on the market, and perfect for the widest range of average users. If you're choosing between this pad and the bigger Klymit model, and have any concerns about comfort, go with the XL. In a large pack, the few extra ounces are definitely worth the amazing comfort the XL provides.

I'm a complete convert to Klymit - never going back to any other brand. All their models earn five stars from me, without reservation. (Posted on 12/2/-1)
God Bless Review by Daniel
If you need to save weight on your back and space in your pack then this mattress is for you. This is great for ultralight backpacking. I can also fit the Klymit Cush pillow in the stuff sac and together they weigh about the same as a can of soda and are about the same size. A great combo for hiking. Now I only give this item 5 stars as an ultrlight mattress. If you don't care about weight or size this one is not for you. It works best if you sleep on your back and is narrow. You can sleep on your side and it still feels ok. I have not used it in cold temps but it is not rated for winter. If you need a bigger mattress or plan to sleep on big rocks, get something else. This is great for ultralight use but for car camping it is a waste of money. And yes, I am buying more X Frames for my family to hike with and Therma rests to car camp or winter/short hikes with.

My walk about Review Review by Down-Under Hiker
I used this product for bushwalking in Australia especially where a lightweight pack is required. Last weekends pack carry was in the high country in Victoria in an area which is subject to extreme weather conditions. Sunday night temperatures were down to 0.C (32 F)with heavy showers. The Inertia X Frame proved to be very comfortable, warm despite the fact a silk liner was used in lieu of the usual thermal liner. My fellow walkers were very skeptical at first as to the comfort of the X Frame but those who tried it gave it the thumbs up. (Posted on 12/2/-1)
Worth it Review by Jeremiah
The real question is does it work and is it worth sleeping on? The answer is yes to both questions!!!
The Inertia X Frame sleeping pad has been one of the most fun gear reviews that I have done. Everywhere I have taken this pad people have looked at it and wondered what is was and then if it worked. I have had a dozen or so people try it out for themselves and tell me what they think. I have also slept on it many times to see how comfortable it really is. I have yet to see someone that was not impressed by what they saw and felt. I was quite impressed though at how the pad supported me while on my sides or stomach, as well. I slept good the first night and even better the second. Klymit has figured it out. This is a great pad for anyone who is trying to save weigh but still have some comfort. (Posted on 12/2/-1)
Where have you been Review by Oversea's Soldier
I bought this solely because I hate luggage around massive bags that take up all of my backpack space. I Read that this rolls up to the size of a soda can so I got it. Long story short it does. The only thing I hate is that I didn't know about this sooner. (Posted on 12/2/-1)
Dilemma Answered Review by Steve
I want to be clear straight away that this pad is the answer to an ultra-lighter's dilemma when it comes to whether or not sacrificing comfort is worth a few extra ounces.
Klymit has no doubt firmly placed itself as a company that is not holding back when it comes to possibly re-inventing the wheel er, ah, the sleeping pad.

I want to be clear straight away that this pad is the answer to an ultra-lighter's dilemma when it comes to whether or not sacrificing comfort is worth a few extra ounces.

But to be honest I think they should bill this as a "one size fits most". If you really think about who the market for this thing is, the ultralight fast packers, it is a godsend insofar as now there is a viable sleeping pad that weighs virtually nothing and allows so much more comfort than most are used to. What is more than that is as folks try it I am sure they will become converts as well, it is too light weight and too practical to ignore....For the record I slept on it on my side, back, and belly and it performed a lot better than my preconceived notions. I can't wait to see what else Klymit has coming out for us in the coming months. (Posted on 12/2/-1)
Tiny Review by Burt
I have used Therm-a-Rest sleeping pads for almost 30 years (I have four in my camping closet, of different ages, colours and weight) but this past summer I decided to try to lighten my pack. I was going on a 7 day backcountry trip with my athletic 34 year old son, and sedentary Dad was not going to be shown up (too much:-). Since pride required that I carry half of the joint gear/food, I decided to cut down the weight of my personal gear, so as to reduce the embarrassment of trying to keep up with him.
I got a lighter pack and sleeping bag, then checked options for a sleeping pad. The Klymit Inertia X Frame seemed to provide a good compromise between weight and comfort, at a reasonable cost.
Unlike Gearkopf, I slept on top of the X Frame, since I toss and turn like a dervish, including often rolling my whole sleeping bag over. Even on a Therm-a-Rest I often find myself well off the pad! Had the X Frame been inside the bag, it would likely have ended up on top of me:-).
Before going out, I slept two nights on a hardwood floor and realized that you have to watch how much you inflate the X Frame. The first night I pumped it up too firmly and it was not as comfortable as on the second night when I made sure it had some give. I (Posted on 12/2/-1)
Japan motorcycle touring Review by Isaac
I bought this for motorcycle touring and camping in Japan. Being tight on space this seemed like the perfect choice.
It was, overall, fairly comfortable. I usually have difficulty sleeping on my back, however it wasn't all that uncomfortable on the XFrame. I didn't find it that bad to sleep on my side or stomach with a little bit of effort.

I love the concept, i love the space saving. (Posted on 12/2/-1)
No Regrets Review by Barrett
I needed a replacement pad for my aging 3/4 insulated one but didn't want more weight. After a bunch of research I settled on the Klymit Inertia XL pad. At just one pound it was the same weight as my old 3/4 legth pad but in a full size, it also packs down to less them half the size of the old one huge bonus.
OK that's enough about the pad let's talk about me for a sec, I am not a small guy at 6'1" and 240 pounds (mostly muscle)but 240 is 240 no matter how you look at it. This being said this pad offers plenty of room and support. The first night I got it I did a test run in the yard, when I woke up in the morning it took me a second to realize that I was outside and not in my bed. This is how comfortable this thing is.
I've since had it out in the field and I tell you that I've never slept so well. As far as warmth goes you'd be surprised how well it does because of the cutouts that allow your sleeping bag to loft uncompressed. I slept in a 20 degree down bag with nighttime temps dropping to the high 30's and didn't have a problem. I can't wait to see how low I can go later in the season.
In closing awesome pad buy it, if your on the fence buy it, you wont regret it. (Posted on 12/2/-1)
Awesome Review by Johnny
The Klymit Inertia X Frame sleeping pad is awesome. If you're a minimalist, the only way you could go with less is to not take a pad at all. I love the way this pad allows my down bag to retain some of its loft below me, keeping me much warmer. I can't speak to "non-slip" because I used straps on my sleeping bag to hold it in place. I also can't speak to its durability yet since I only recently started using it; time will tell. It is quick and easy to inflate and deflate and does indeed pack down to the size of a soda can. I will combine this pad with another thin pad in more extreme conditions or when I want to go "cushy". It is in a word....awesome. (Posted on 12/2/-1)

Easy to Inflate Review by Cameron
Just got this. I have to say I was a little skeptical at first. I did a little test and sure enough it inflated after 4 - 5 breaths (way easier that my other pad that takes a solid minute of inflating). I then used the included bulb pump to get a little more pressure in it. I set it on the concrete garage floor and it felt just as good, if not better than my full pad. It easily takes up less than a quarter of the space too. I am feeling a little better about this purchase now. (Posted on 12/2/-1)
So far not disappointed Review by Harrison
Took them out to BWCA couple of weeks ago and they preformed great. I've tried several pads before and the X frames worked the best. Look a little strange and my wife was skeptical, but after the trip she said they were the best compact pads she has used. Thought they might slide apart at night, not in our case. Strapped the frames together the first night, than decided to try without, couldn't tell the difference. I'm about 160# and wife, well big secret, but less than my weight. I considered other mats but for about the same price I bought these, and so far not disappointed. One did deflate unexpectedly one morning, couldn't find a hole in the pad, and decided it must have been the hand pump. Worked fine the rest of the trip. Weight with little hand pump is 10.6 oz. without is the 9.1 (Posted on 12/2/-1)

Really like this pad Review by Jerrell
Purchased the X-frame in March of this year and received it at work. The pad weighed in on the postal scale at just over 9 ozs. I had to work really late one night and slept on the concrete floor with just a sheet comfortably. It came with a pump to firm the mattress, but I did not need it. Four breaths and it was fully inflated. I just returned from a 9-day pack trip to the Bristol Head area of southern Colorado. The X-frame preformed well on the rocky ground. I tend to be rough on equipment, but the pad showed no visible signs of wear, so I did not try the patch kit that came with the pad. It cleaned up easily with soap and water when our trip was over. I have minimalist tendencies, so I was quite pleased when the pop can sized pad disappeared into the sleeping bag compartment with my 2.2 lb sleeping bag. I am 6'3" and weigh about 200 lbs. I sleep mainly on my side, and found the x-frame to be quite comfortable. Even when the ground was inclined, I did not slide off the pad like my 3/4 Therm-a-Rest. I had my doubts about the comfort of the cutouts in the pad, but after the 1st night, I didn't think about it anymore. Several in our group will probably purchase one before our next outing, they were impressed with the speed to inflate or deflate the pad, the lite weight, and the little space the pad consumed. I have been a hiker for a little over 40 years now and really appreciate a little more comfort between me and the ground. The temps only got down to 30 one night, so I could not make a judgement about the cutouts adding to any extra thermo abilities. The price was more than I wanted to pay for a sleeping pad, but the benefits of space and weight eased the pain considerably. I really like this pad. (Posted on 12/2/-1)

Conviced Review by Jared
The Klymit Inertia X Frame is an anatomically patterned, super light weight (9.1 oz) camping pad that packs down to the size of a soda can. Looking at its unusual shape makes one wonder if such a thing is possible to sleep on. Klymit has made some revolutionary changes to the standard inflatable pad, and the result has many people scratching their heads. But I slept on the X Frame during a winter camping trip, and found that this pad is worth far more than its tremendously low weight.

Need to consider Review by Vitto
I want to be clear straight away that this pad is the answer to an ultra-lighter's dilemma when it comes to whether or not sacrificing comfort is worth a few extra ounces. Most fanatics will go to such extremes as filing down their gear and removing extra padding or straps from their packs, they push to carry less weight for a number of reasons, but regardless of what drives the individual it is important to know that Klymit has taken notice and worked hard to develop a means to insulate a person from the ground as well as comfort their slumbers. lacking.

The basic idea is that most sleeping pads, like your home mattress is essentially wasted material. Your body only has a few actual contact points to the surface when you are sleeping and Klymit has whittled away all of the unused materials to create this skeleton of a mat. At first glance I thought "what in the heck is this thing" and "it must be another hair brained idea made by lab rats with no real world camping experience". Well I couldn't have been more wrong.

When I laid down on this mat I was actually amazed that it was padded right where I needed it. Sure there will be some folks that it just doesn't feel right especially due to the varying lengths and individual phenotypes of people. But to be honest I think they should bill this as a "one size fits most". If you really think about who the market for this thing is, the ultralight fast packers, it is a godsend insofar as now there is a viable sleeping pad that weighs virtually nothing and allows so much more comfort than most are used to. What is more than that is as folks try it I am sure they will become converts as well, it is too light weight and too practical to ignore.

One of the lesser appreciated features with this pad is that the phrase "less is more" actually applies, you see all of those cut out areas actually allow your sleeping bag to keep it's loft. After all loft is why your bag is able to keep you warm in the first place. Compressed insulation is worthless, but fully lofted insulation has optimal heat retention properties. Aside from the amazing and well thought out channels the Klymit folks decided to provide 2 methods for filling the X Frame, the first is the usual air mat method of blowing into it (took me 3 full breaths) or with an included hand pump which allows you to fill the mat fuller than through lung power alone. And with the highest burst rating of any mat at a full 10psi I have no doubt you can get this thing to support you well enough for it to not be a concern. The Inertia X Frame packs down to the size of a beer can (12oz not the big 24oz ones). Which in turn will no doubt free up some cargo space so you can, well, carry more beer!

So regardless of if you cut off your toothbrush handles or you bring a cast iron dutch oven on your trips, this product is one that you need to take the time out to consider. Bigger folks may want to give it a go in the store first so you know if you are going to hang off of the side. Yes it might take some time to get over the psychological impact of "less is more" but the folks at Klymit did their research. For the record I slept on it on my side, back, and belly and it performed a lot better than my preconceived notions. I can't wait to see what else Klymit has coming out for us in the coming months.

Seriously Review by
In preparation for my Grand Teton trip I had reached out to some awesome companies and had gotten some awesome gear to use. Unfortunately the trip was a bust, but I've had the chance to test out the products nonetheless! One of those products was a sleeping pad from Klymit.

I had seen pictures of the Klymit sleeping pads online and had thought to myself "They can't really be comfortable!" So when the OR Show rolled into town, I made sure Klymit was one on my list of companies to check out. I laid down on one and quite honestly, after walking around all day, I didn't want to get up!

Klymit utilizes a unique body mapping technology to provide cushion in all the right places. Here is what their website says:
