Inertia XL

A technically advanced pad for those who want to travel fast and light but love their comfort, the Inertia XL is the lightest, most compact oversized pad available. Packed with comfort features – a built in pillow, a wider sleeping platform, customizable pressure and support – it still weighs in at only 14.1 ounces and packs down to soda can size. Deep welds up the thermal efficiency, and patent-pending Loft Pocket Technology positions the chambers to maximize your sleeping bag’s performance while minimizing pad weight.

  • Body Mapping: Advanced patterning places chambers only where padding is needed and eliminates them where they are not, allowing us to shed significant weight without sacrificing comfort.
  • Loft Pockets: Empty spaces between the chambers serve as expansion zones that allow your sleeping bag to fully loft beneath you, maximizing its thermal performance.
  • Inflation and Deflation: Pad rapidly inflates in as few as 5-7 breaths, and a hand pump is included for more rapid inflation and the ability to reach a higher PSI. The valve’s intelligent design allows for micro adjustments to fine tune pressure and comfort.
  • The Right Size: At 78” long, the streamlined size is tapered to fit the body and allows the pad to be used inside or outside of your sleeping bag.
  • Ergonomic Had Support: Comfortable, secure head support is integrated into the pad’s design.


  • Rugged Material: The hybrid construction combines an exceptionally lightweight 30D polyester top with a 75D polyester bottom for superior tear, puncture and abrasion resistance where it’s needed.
  • Patch Kit: Included for emergency repairs, a patch kit comes stored in a small integrated pocket on the top of the pad’s storage bag – already packed and always at hand.
  • Storage Bag: A storage bag, sized specifically for your pad, is included to maintain compactness and provide protection while traveling.


  • Minimalist Design: Advanced patterning removes all extraneous material to creates an ultralight, minimalist design that delivers comfort and support for only 14.1 oz. and packs to 4" x 8".
  • Ultralight Material: Used on the top of the pad, the 75D polyester material sheds grams while maintaining appropriate durability.

Hi, I bought an Inertia XL one to two years ago and then due to a series of unfortunate events, I was unable to use it until this weekend. I blew it up and used the hand pump and went to sleep happy, but woke with it flattened - had to reinflate it four times on first night. I took it home and filled the tub and immersed it and could see a slow bubble escaping from valve. Can this problem be solved?
Thank you, Anne
