Quick Overview

4.5 oz / 128 g - Lighter, stiffer, and great load transfer for your pack. The Klymit AirBeam Pack Frame is the solution to allow you to move more comfortably on the trail by replacing your removable pack frame in your current pack.
AirBeam Pack Frame


The pack frame designed for movement


1. Lighter- at 4.5 oz the Klymit Air Beam is a fraction of the weight of most pack support systems

2. Stiffer- by utilizing our proven lightweight fabrics we can achieve incredibly strong structures supported by pressurized air

3. Optimal Load Transfer- at only 1 in. thick the Klymit Air Beam keeps the load very close to your back for direct transfer to the hips

4. Allows you to MOVE- climb, contort, and even tie your shoes easily

5. More comfortable- conforms to shape of back, dampens vibrations, decreases fatigue

6. Increased adjustability- For each individual pursuit you can change the pressure and dial in your stiffness/ flexibility and optimize your pack for the situation and load

Who Cares? Why?

Problem: Backpack frames are rigid and designed to transfer load directly to the hips, yet because they are rigid they only transfer directly when the body is in one, or a limited number of positions. Load transfer to the hips fails under movement and contortion of the human body. Nearly all major pack manufacturers have attempted to solve this problem with swivels and pivots, and thus compromising load stability during movement. Pack frames are heavy, inefficient under many conditions, and due to the advances in lightweight camping gear, much of the weight of a backpack load is the pack itself.

Solution: Using superlight fabrics and pressurized air Klymit has developed a backpack frame that transfers load to the hips even under movement and contortion of the body in a wider variety of conditions. It allows the user to decrease their pack weight yet increase both comfort and pack rigidity at the same time. The weight of the AirBeam Pack Frame is about 3.2 oz

Unique aspects of the Klymit Frame
1. This is the first framesheet that has a positive correlation with load. Up to 40 pounds the framesheet gets stiffer as the backpack load increases.
2. The concept rests that under medium to high pressures (4-10 psi) the framesheet resists horizontal collapse, allowing for chambers of air to maintain vertical orientation and allow gravity to force pressure downward directly to the hips for optimum load transfer.
3. This is the first framesheet that is vertically rigid to maximize load transfer, but compliant during motion and conforms with the human body during strenuous activity, and allows malleability for simple tasks such as bending over and tying your shoes.
4. This framesheet was designed to increase comfort while decreasing weight, and to sacrifice nothing in rigidity and load carrying capability.

Slow leak Review by Andy
I've had my pad since new 9 months ago but unfortunately from new it only holds meaningful pressure for 2 hours at a time. I'm stuck with it as I live in the UK and shipping would be expensive even as light as it is. Looks like I'll be returning to HDPE plastic sheet and CCF roll mat sandwich!

Klymit: Sorry to hear about the issue you have had with your Airbeam Pack Frame, It sounds like you have a manufacturing defect in your valve, If you contact our warranty department at we would be happy to work something out so you can have a fully functioning pack frame (Posted on 9/7/15)
Nice and Light, Get a Spare Review by Ian
We've had 1 pad that has lasted for months, one had a hole in it on delivery, the replacement lasted a couple outings before it developed a slow leak. It definitely helps lighten the pack weight and feels comfortable. Needs to be a little more durable.

Klymit: Sorry to hear about the issues you have had with one of your Air Frames. We take pride in the quality and durability of our products, All products have a lifetime warranty, Email us at and we will be happy to take care of the issue (Posted on 6/20/15)
Button problem Review by Whiteburn
The airbeam does what it says in helping a lot to carry 20+lbs. One niggle is the push button deflator, had it accidently operated on a couple of occasions by pack contents, a bit annoying. The button needs a redesign to prevent this or a simple cap.

Klymit: We have noticed this slight issue and are working to find a permanent solution. Look for an updated version in the near future. (Posted on 12/5/14)
Airbeam Frame Review by Rock and Ice
We did blind tests with the air frame…and a rigid frame. No one noticed any difference in load transfer to the hips, but each climber said that the air frame allowed more freedom of movement.

Trailspace Airbeam Frame Review Review by Seth
Overall I found the Airbeam to be:

More laterally flexible and comfortable than my HDPE plastic frame sheet.
Multi-purpose – it also functions as a sleeping pad extender or topper, a pillow, or a backrest with my pack against a tree.
Good initial quality and performed as promised.
Installed inside the pack, the Airbeam didn’t seem to affect the air circulation between the pack and the wearer.
Very useful for adding structure and comfort when installed in my older Echoroba frameless backpack.
The pack was slightly more prone to “barreling” if I over stuffed the pack than it was with the plastic frame sheet.
I found it difficult to get every last bit of air out of it, the spring loaded deflation button requires constant pressure from a finger to remain open. I had to roll & squeeze, then press the button to let air out, and repeat until empty. It’s not like the kind of valve you unscrew to open and screw back to close.
