Klymit Inertia X Frame
Ultralight, Ultra Compact, Comfortable and Durable
The lightest, most compact, full-length sleeping pad ever developed, weighing 9.1 oz with a pack size smaller than a soda can.
Built to Last
Built for fast and light three-season backcountry use, the Inertia X has a light, tough 30d ripstop top paired with hard wearing 75d bottom that makes it one of the toughest pads around.
Comfort in Mind
The body-mapped design provides comfort and support at key pressure points while eliminating unnecessary material that can add weight and bulk.
- Weight: 9.1 oz
- Inflated Dimensions: 72" x 18" x 1.5"
- Pack Size: 3" x 6"
- Inflation: 3-5 Breaths
- Material- 30D Top/ 75D Bottom Polyester
Inflation and Deflation:
Pad rapidly inflates in as few as 3-5 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 72” long, the streamlined size is tapered to fit the body and allows the pad to be used inside or outside of your sleeping bag.
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.
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.
A storage bag, sized specifically for your pad, is included to maintain compactness and provide protection while traveling.
Advanced patterning removes all extraneous material to creates an ultralight, minimalist design that delivers comfort and support for only 9.1 oz. and packs to 3”x6”.
Used on the top of the pad, the 30D polyester material sheds grams while maintaining appropriate durability.
Body Mapping Patterns
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.
Empty spaces between the chambers serve as expansion zones that allow your sleeping bag to fully loft beneath you, maximizing its thermal performance.
Deep Weld Patterning
Unlike traditional pads that flatten the bag’s fill, Deep Welds create expansion zones that allow your bag to fully loft beneath you for improved thermal comfort.

- Very lightweight and packable. I can easily fit the pad, its "bulb" inflation pump, a repair kit and my inflatable pillow into the included stuff sack, which is slightly bigger than a 16oz can, but less than a 32oz Nalgene.
- Surprisingly comfortable and warm for a minimalist design. As a fairly big dude and a side-sleeper, I was pretty pleased to not have more sore spots in the AM.
- Customer service for repairs has been good. I never had to bicker with Klymit about repair issues- they honor their warranty.
- Turnaround for repairs has been reasonably quick.
- Initial purchase was cheap; not a great long-term value though.
CONS: My overall impression is that this is a good concept prone to suffering from manufacturing shortcomings/seam defects. My pad first split at the seam near the calf support cross pad on the first night of my second trip with it. No slow leak over the night; totally flat within a minute. 4 more nights of sleeping on clothing after that. Patched it with the enclosed repair kit in the field, but it just wouldn't fix. Once home with enough time for a decent patch job and curing time, I went overboard on the seam glue as a precaution after the first repair job had cured. Used it for a 3-day trip using my hammock afterward with some minor deflation (likely a pinhole leak from my home repair). Not a biggie, since the hammock was comfortable and it was warm enough to not need to loft my sleeping bag through the pad's design. I did the soapy water immersion test with it, and fixed any tiny bubbles with seamgrip and aquaseal. Dried it and double checked to make sure there were no leaks. The rest of my camping that year was within 2 miles of trailheads and I opted to use a thicker pad for comfort that season.
Fast forward to the first trip of next camping season- a month-long backpacking roadtrip from the PNW to Boulder. I had one or two pinhole leaks during the first half, easily fixed with seam grip and some tenacious tape (I packed prepared for smaller problems). The calf support cross pad again delaminated, this time on the upper portion in a different segment. This time at Nelson lake on the Belly River trail in Glacier Nat'l park, 10+ miles away from anywhere close to comfortable.
I sent it back to Klymit's HQ after that trip for a full review of leaks and repairs. They sent it back within 15 days of my return. I did the soapy water test and left it inflated for a few days in my garage, with no discernible leaks. Their customer service and warranty honoring is good, as far as I have experienced.
And then I went to use it last weekend in the PNW (5/19/17 for future readers)... Three hours after racking up, the nylon splits at the base of the support pad, through another seam, near my right ankle and ran for around an inch towards the end of the pad. This time it was a clean tear through two layers of what should be ripstop nylon. For those inclined to ask for clarification- no, there were no sharp objects at the foot of my sleeping bag. A friend only out for the first night loaned me his Nemo Tensor for the remainder of the trip. No rips, no delams and a good night's sleep, other than some crinkling sounds from a colder weather pad.
I've prob spent an extra $30+ on top of the initial $60 I paid for this pad in repair materials and shipping back to Klymit for manufacturer's repairs. After last weekend, I bought a new pad from Thermarest's NeoAir line and am giving up hope on this pad. I'll be losing some packability and gain about a pound in pack weight, but it's worth it to me to have a good night's sleep that won't pop.
I would not recommend this pad until they iron out some of the kinks in their manufacturing and design. For instance, you can look at the overview of the pad and see 4/5 of the crossbars use baffles. By leaving them out in the area around a user's calves, I imagine they hoped to save some weight in baffle glue and some $ in manufacturing. What I think happens in the field is that it leaves an area particularly vulnerable to delamination and popping. Much like the two delams I've seen in the field.
This is only my experience with this particular pad. Like I said before, there may be some benefits to you. My experience has been overly negative and this review is only my heads up to others who may not be as informed as I was pre-purchase.
As someone who's 5' 4", this sleeping pad works well for me, but I can see it have several drawbacks:
1) The pad is "body mapped" to fit someone is about 5' 10" in height. Thought the 6 inch difference does bother me, depending on how your body parts match up to it, the pad may not fit you.
2)The pad is also only 18" wide as opposed to the standard 20" width, so it's quite narrow. You are not going to have much room to move side to side.
3) The pad is ideal for people who sleep on their backs. If you turn over frequently, sleep on your side, or curl excessively, this is gonna suck.
I finally got around to purchasing one. Delivery was quick and I took it out the following weekend on an overnight backpacking trip. It completely leaked within the first 15min.
Thank goodness I also took a sleeping mattress.
When I brought it home I tested it and checked for the leak in the bathtub. It was leaking from the hand pump valve.
Contacted Amazon and they sent me another one right away.
I received the new one and it had the same leak from the Hand Pump Valve.
Klymit should address their Quality Control.
I kept the second pad and took apart the Hand Pump valve to see what the problem was. Unfortunately, the valves are not rebuildable without breaking it due to it being put together with glue.
But I found out that either the internal O-ring is not soft enough, or the spring is not strong enough.
I was able to rig something up to be able to use the pad, but I cannot use the Hand Pump.
I really like the mattress itself and the weight. But it's unfortunate for the bad valve, bad quality control, and the initial headache.

The design of this receives 5/5, unfortunately the execution of the product receives a 2/5 which is ultimately what this is based on. For a product this expensive I do not recommend buying it.
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 :)
It is comfortable, it looks unlikely but it really is.
Small, lightweight and cheaper on here than camping shops
I love it
