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. I found the X Frame on Amazon for a third of the price my local store wanted. 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.A word on the hand pump, it is different to the one pictured. I emailed Klymit and they informed me the new pump is much more durable and actually smaller than the old style. It is also flat black (not glossy like the one shown) and does not feature the Klymit logo (ink run was an issue). The new design allows you to keep the pump attached to the mat at all times (although I still prefer to remove it) and apparently does not freeze in extreme environments (the larger pump had a reputation for this).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.

I've slept on this about 10 times now, on mountains, on the sand, in meadows. I backpack a lot and really wanted something lightweight. I can sleep comfortably on my side, my back, and my stomach. One night was up on a mountain where temperatures got around 35 degrees, the pad worked fine.You need to sleep with this inside your sleeping bag, and for your own comfort you should also use a sleeping bag liner or roll yourself in a bed sheet, this will help retain a lot of the "lofting" component of this pad.Positives:- WEIGHT. It's stupid light, just a couple ounces.- COMPACT. It rolls up to a small size, although rolling it up isn't elegant.- COMFORT. Comfort for me is a 8/10 considering the size.I've definitely used more comfortable - again, just make sure you consider this as part of a 3-part system: your bag, this pad, and a liner. If you don't use a liner than your arm or knees will fall into the crevasses and touch the ground - it's not totally a problem, just less comfortable.- COMPLETE. Manufacturer includes a patch kit which fits into the stuff sack, good touch for the price point.- AESTHETICS. I really dig the color of the pad and the packaging, I'm a vet that likes low visibility stuff when outdoors. That's also sort of a con with this thing when it comes to the inflation device which I'll describe below...the inflation device shouldn't be black, it should be higher visibility.Negatives:- INFLATION. The inflation system is dumb. There isn't a check valve to inflate the pad, just a twist valve you can blow into and then close quickly to retain some of your breath - 5-6 breaths is the maximum to inflate. Even if you do this "perfectly" and close it with maximum air you can jam in there it's still not enough. Making the inflation valve a one-way check valve would easily bump this up another .5 stars. Inflation time for this sleeping pad is about 60-90 seconds: 5 good breaths and then 30-50 pumps. It has this really stupid inflation ball device *that you must hold on to and use each time*. When you're warm and fed it's easy to install this inflation device, but god help you if you're shivering from being tired, wet and cold. Honestly, the entire inflation system is just god awful dumb. A pad should only take 30-60 seconds to inflate, and you shouldn't need this little ball. If you lose the black inflation ball device, this pad is worthless. I know I'm going to lose that device eventually.- DEFLATING AND ROLLING. Rolling this thing up into it's most compact size takes experience and patience. It doesn't easily fold in half or quarters or thirds....ideally you fold in thirds, but the material wants to slip out.... Again, rolling should be an elegant process, and making a few manufacturing changes to the pad should make finding creases easier.Still, I'm very happy with this.

Bottom line: Mine failed the second night had it in the field, but the first night exceeded my expectations.I really like the X-frame concept. It removes a LOT of unnecessary weight, yet provides a good level of comfort. I'm a tarp and bivy kind of guy, and I was excited by the prospect of putting this pad to use. My first night out with it I was very pleasantly surprised by how comfortably I slept. I'm 6'4" and it worked just fine for me. Comfortable sleep and it held air all night.My second night with it was a different story. It wouldn't hold air for more than a couple hours. I have been careful to follow Klymit's instructions and not lock the cap while inflating, so I didn't pop a seam.

I love this mat. I was in Alaska over the summer doing lots of camping and hiking and I brought a flimsy foam mat with me but it was just no good as it was big and bulky when rolled up and I still felt like I was lying on the ground with no mat as it was so thin.On one of the trips I went on my friend let me borrow his Klymit Inertia X Frame as he wasn't able to come with us and I was complaining about my crummy mat....What a differenct it made! It took up no room at all in my backpack as it folds up so small and as it is sooo lightweight it hardly adds any weight to the load.There isn't much to it but it was still comfortable even after 2 weeks of use every night.

Nice and small but not a big gain on my old short neo air xlite. Due to packing light I never really got on with putting my bag/clothes under my feet for lower leg insulation so I got this for the length. I’ve got the coyote version which I think is a little thicker (heavier) construction and seems more robust than my thermarests, no punctures yet. I ditch the pump, I’ll risk the moisture damage as the point of it is to save weight and packing. It’s reasonably comfy for back sleeping but useless if you roll around a bit it’s also increadably narrow hence why it’s best inside your bag, if you can, just to help keep your arms in and stop you wiggling off. It’s certainly not my favourite mat (thermarest xtherm for the win)

I bought this solely for the purpose of saving space in my bag, compared to lugging around a giant awkward foam pad. Not quite as small as a soda can, but not much bigger either. I've used it camping, backpacking, mountaineering, bicycle touring, and on military training missions (combined total around 50-75 nights). It is quick and easy to inflate, easy to pack, has never leaked or had any other issues. Now, I do wake up fairly often either off of the pad (if it is outside the sleeping bag) or with the pad on top of me (if it is inside the sleeping bag), so it's a bit tough to get it to stay put, but it is definitely worth this minor inconvenience.

My wife wanted this but then changed her mind. I gave it to my son. I tested it out and it just doesn't support a 200 plus pound guy enough, at least to my expectation. The biggest issue when I tested it was getting it inflated. You can blow it up quickly with your mouth but to get it firm enough, you have to use the bulb--a little complicated. If you get it firm enough, it will work. I prefer the Klymit Static V but, my son likes this just fine. I don't see the benefit of carrying this one over the Klymit Static V as the size and weight are marginal. However, if you are trying to get the size and weight down as much as possible, this is serviceable if inflated as much as possible.

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.

I used this mattress exclusively on a 9,000 mile motorcycle trip to Alaska where I needed something small and lightweight. It was both. And by putting it inside the sleeping bag, there was no problem with rolling off of it in the middle of the night! But I tend to turn over a lot and I found that it would move around in the bag a bit, causing me to have to reposition it on occasion. The only time it didn't do the job was at an RV campground in Dawson City, Yukon that had rather large sharp gravel, not really designed for tenting. The sharp gravel protruded through the open areas and made for an uncomfortable night. The rest of the time, it was fine. I did have to adjust the pressure with the included 'bulb pump'

Awesome sleeping pad for an avid backpacker. This is the third sleeping pad we have purchased of its kind because it has been a perfect addition to our gear. We just keep adding to our collection for more family members. We all sleep great on this pad. Now you need to remember, this is a very light weight sleeping pad that was designed specifically for backpacking; the major padded areas are for your head, shoulders, hips and feet. You will feel completely comfortable on almost any camping ground. The Klymit Inertia X frame pad fits comfortably inside your standard mummy bag sleeping bag; this is one of my favorite things about this sleeping pad. When you roll over, the pad is still under you to give comfort.

When you look at it you think there's no way this thing can be comfortable. But since it's won awards and whatnot I figured I'd give it a try. It arrived on time and was even smaller than I thought it would be. I unboxed it, read over the literature that came with it and then inflated it. Took three breaths! I then attached the hand pump and firmed it up a little more. That night I decided to test it and used it on the floor with my sleeping bag (slumberjack latitude 40). It did great even for a side sleeper like me. I used it a couple more times at home before taking it on an overnight hike. It has made a huge difference in my pack weight and has performed like a champ.

I bought two of these for a weeks enduro camping tour of the Pyrenees. So size, weight and effectiveness were a real priority. They are definitely small and compact, and the system really works ( one night one of the closures was not shut properly so it went down and that was a good comparison to how well they normally work).They seem to help the warmth and definitely give a good nights sleep. They do move abit if you roll over but once you are aware of that it doesn't seem to happen. These are the full length ones, I wonder if the half length one might move up and down.Plus great customer service :)

I want to report on Klymit's great customer service. I purchased this item in 2013 and it lasted a couple of years then started leaking. I would have to inflate it several times per night. I contacted Klymit and they sent me a new one. The new one began leaking after only a handfull of usages. I contacted the company again and requested a Static V instead of one of these again. They promptly sent a Static V. While I have experienced issues with this pad design, the company has always taken care of the issue. Good customer service Klymit.

Takes a little getting used to but I really like this sleeping pad. The biggest advantage is the weight and size. It is literally smaller than a soda can when deflated and weighs almost nothing. Perfect for long backpacking trips. I put it in my bivy sack and slept like a baby.I should also mention that we got some weather (rain) during the night and I managed to get a pool of water and a slight leak in my bivy sack. But, this pad actually kept me up off the puddle and I stayed warm, despite a wet bunk. So, this is my new favorite pad.

I used the X Frame on my recent hike of Katahdin and the 100-Mile Wilderness. I was very pleased with the X-Frame's performance. It packs small, is light weight and suprisingly comfortable. I used it inside my sleeping bag rather than under it. I found it more comfortable and much easier to use than my self-inflating pad. My only complaint, which for me is a minor one, is that my feet seemed to slip off the end of the pad a lot; but again this was not a big deal. If you need a super lightweight sleeping pad, this is a good one.
