    The Klymit Inertia X-Frame sleeping pad features a unique cut out design and high pressurized comfort that makes it one of the thinnest, lightest and most compact sleeping pads.

    • Klymit uses body mapping to support the key areas, such as the head and hips, and removes padding in less critical areas to reduce weight
    • Cutouts allow a bag’s insulation to remain lofted, which maximizes warmth, rather than becoming compacted between your body and the pad
    • Inertia X-Frame pad can be inflated with just 2 - 4 breaths; to adjust firmness, use the included hand pump to increase air pressure in pad
    • Use it under or inside (so you'll never fall off) your sleeping bag
    • Pad includes a stuff sack, patch kit and dry air pump
    • Klymit Inertia X-Frame sleeping pad rolls up to the sized of a soda can for easy packing
    • Constructed from 30-denier ripstop nylon top and a 75-denier polyester bottom for durability

    Klymit Inertia X-Frame Sleeping Pad is rated 3.3571 out of 5 by 14.
    Rated 2 out of 5 by from just ok - while it lasted... I took it on the Appalachian Trail with me - lasted for about a month - and then got punctured and was completed useless. Couldn't find the hole to patch it. The thing was uncomfortable for hiking 20+ miles and then having this to sleep on. Best pad ever? just a basic non blow up foam pad... or a thermarest that if it does puncture - still has a little padding. If you are careful about where you lie this ultra light frame down and perhaps don't use it too much - then maybe it's good for you - but my opinion for what I was doing - no bueno.

    Rated 5 out of 5 by from amazing, warm, works side sleeping 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. its easy to inflate, packs down to the size of a red bull can, you could carry it in your pocket.

    Rated 4 out of 5 by from It works... You really can't argue with how great this thing compacts...and it is super lite-wt. It is an odd-looking contraption for looks like a birthday balloon clown put it together as part of his act...but it works great. I used it for a ten day back-packing trip into the northern Talkeetna's and I was thankful for it. Wt. was definately a factor for me, which is the reasonI left my exped at home. This odd looking pad takes a little getting used to (finding the right spot to rest your hips when you roll on your side), but I really adjusted to it quickly and slept well on my back and sides. I did come off it a few times, but no big deal. I'd do it all over again with this pad no problem.

    Rated 4 out of 5 by from MMMMMMMMMM, Not for Me Super lightweight and packs down small so was hoping this was the pad for me. Then I slept on it. I move around too much in my sleep, going from back to sides and back again. I'd start off the night comfortable enough but would wake up many times during the night trying to find that comfort spot again. I won't give it a horrible star rating because I don't think this is a bad pad, I just don't think it fits my frame (5'8") and style of sleep. Definately check this out in the store before buying (Unfortunately I didn't) and try it at home or car camping with a back up pad before a backpacking trip--yep you guessed it, I didn't do that either.

    Rated 5 out of 5 by from Cool Pad 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.

    Rated 5 out of 5 by from I got this as a gift and love it. 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.

    Rated 1 out of 5 by from Built for speed, not comfort This weird looking pad sucked me in at its low weight and its premise that deleting tubes would allow my sleeping bag to loft in the space to insulate me from the ground. I spent two nights on this pad on my living room floor. I can't address its insulation value, as I won't take this mattress camping. AT my height, 5'8.5", this kind of worked for me if I kept myself a few inches below where my head should go on the mattress, i.e. the pad had 10 tubes to support my shoulders, hips and feet. The big BUT is that removing support tubes required the remaining tubes to support the same weight as before, translating to more pressure on the body parts that contact them. That made side sleeping a sensory nightmare for me when I flexed my hips and knees--continuous pressure morphed to pain at the contact points where body parts crossed the tubes. It hurt my wimpy limbs. I achieved some relief if I lined up a calf or thigh with the tubes, but that required staying aware of body position, which didn't permit a solid night's rest. I have tried changing the amount of air filling the tubes with no improvement. I didn't sleep well on my back either. I had this mattress under my sleeping bag, and I know that using the pad inside my bag wouldn't have addressed the issues I had. The 1.5" thickness is a huge step in the wrong direction from the 2.5" mattresses with which it fails to compete on any measure but weight. To sleep well, I must have support for ALL parts of me. The inflated pad is 16" wide, NOT 18" wide, and average sized as I am, my arms kept falling off when I "slept" on my back. I returned to my 12 ounce Peak Elite AC for the rest of the second night and confirmed it as the supreme cloud and as good as it was for 9 nights on the Wonderland Trail last August. For me, lighter is the enemy of good.

    Rated 1 out of 5 by from Great in theory, but... I bought this sleeping pad one year ago to use on my summit bid of Aconcagua (22,841'). I was really trying to shave weight and bulk from my backpack (unlike Kilimanjaro, porters aren't generally used to schlep everything up this mountain), and this sleeping pad does blow everything else currently on the market out of the water on those two fronts. However, after just one night on the trail, it be came very clear just how uncomfortable this sleeping pad was, and I'm very surprised to see all the great reviews detailing the comfort of this pad, because that wasn't my experience at all. First, the areas of support have to fit your body almost perfectly: if you're not an average build 6'0" man, your weight distribution and shoulder/hip hitting points won't match up with the supported areas of the pad. (I thought that I'd be ok, because I'm an average build 6'0" woman, but apparently if you don't have the right torso to leg ratio, your hips won't hit at the right spot.) Second, don't expect this sleeping pad to provide any kind of warmth or relief from cold ground. I slept with a closed-cell pad (the Therm-a-Rest Z Lite Sol) underneath this sleeping pad to help protect against the cold ground, but the "holes" in this sleeping pad due to the design allowed cold air to seep straight up into my sleeping bag. I had read that the solution to this problem was to put the sleeping pad inside my sleeping bag, so that the down in the sleeping bag would "loft" and fill those areas of the sleeping pad: but the actual sleeping pad has some kind of chemical residue or treatment on the surface which was pretty irritating to my skin (even though most of my skin was covered when I was in the bag). Regardless of the irritation, I didn't find that putting the pad inside my sleeping bag did much to improve my warmth during the night, either. Third, I disagree with previous reviewers about this pad being okay for side sleepers. I am a side sleeper, and every time I switched sides during the night, my sleeping bag would slide off this pad's optimal positioning (for shoulders, hips, etc.), and this pad would slide off of the closed-cell pad, so that I didn't get good sleep because I'd wake up when I slid off the pads onto the cold ground. I finally had to duct tape the sleeping pad to my closed cell pad, just to minimize the sliding. Suffice it to say, I wouldn't buy this again, even though it definitely beats a more traditional mattress on weight and packability. In fact, when one of my teammates had to turn around on the eighth day on the mountain, I begged him to trade this expensive, high tech pad for his older but more traditional sleeping pad, so that I would be able to get better rest for the remainder of the trip. (Thankfully, he agreed, and seven days later I reached the summit of Aconcagua!) I wouldn't recommend this sleeping pad to any friend of mine. Instead, I'd recommend the sleeping pad one of my fellow climbers used on the trip, which I'll be buying for my Denali climb next year: the Therm-a-Rest NeoAir XLite. It seemed to be the next best on weight, it packed down just as well as this pad, and it offered significantly more stability and warmth.
