Item #KLYMITINERTIAXFRAME

Inertia X-Frame

Ideal for 3 season use when used by itself, the Inertia X Frame rolls up to the size of a soda 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-inflate pads. The cut out regions of the pad not only reduce the pad's bulk and weight, but is the basis for Klymit's patent pending loft pocket technology. 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, while promoting breathability. Built with ripstop 30d top and coated 75d bottom, the Inertia X Frame is also one of the toughest pads on the market with a burst pressure of over 10 psi.

Chris - When I first pulled out the Inertia X-Frame I thought to myself "the future is here!" The innovative design puts padding only where you need it and allows the loft of your sleeping bag to insulate through the empty spaces in the pad. The first night I used it, I inflated it by mouth and then pressurized it with the included bulb pump. I ended up sleeping horribly on it--waking up off the pad over and over. I woke up the next morning feeling a bit worked (after our 26 mile first day) and disappointed. The second night I used it, I only inflated it by mouth. Right away I could tell that the pad was staying in place much better, and I was just as insulated. That night I slept with no problems and realized that I may have unconsciously been worried about all the empty spaces in the pad which made me think I'd have to pressurize it until it was rigid. It definitely works better with less pressure--it simply hugs your shoulders and hips better which keeps you in position on the pad most effectively. The design really challenges your assumptions about what makes a sleeping pad work, but I won't hesitate to pack this pad for my next fastpacking trip--the proof is in the comfort while sleeping and the extreme compactness(smaller than a soda can) and light weight (less than 10 ounces for a full length pad!)

Howie - This sleeping pad is the full length version of the Klymit X-Lite. Kudos to these innovators for figuring out how to improve a product that everyone needs by stripping it down and making it lighter. It is kind of like how we all know a donut is better than a Danish. Unfortunately, in this case they went a bit too far. The holes on this pad are way large. To keep from touching the ground you really need to be both an immobile back sleeper and the perfect height. One of our testers was able to make this pad work well by folding it in half and using their backpack under their feet. I guess you could bring 2 pads, eh" This one has the same drawbacks of the X-lite in terms of limitations on wet or snowy ground, but more so since the holes are larger. I think of this pad as a beta version of a product that they are going to create very soon that everybody is going to want. Until then I would steer clear of this pad. Go with the X-Lite for summer ultralight adventures, and get another pad for winter. Either that or plan to use this one with a second ensolite pad for a winter setup.
