I hate to start out with the conclusion, but that is our conclusion after using the Klymit Inertia X Frame sleeping pad for several months.

I begin my testing in the early spring when temps at night dipped to about 20 degrees. I typically get cold at these temperatures with other air sleeping pads that I have tested…So I was very skeptical that with this pad that has NO R rating, or in other words NO insulation, that I would be able to stay warm.
The first night at these temps I stayed quite warm with my 0 degree rated Sea to Summit bag. I attributed the warmth both to the good bag, but also to the design of this great pad.

Klymit has designed this pad to have huge spaces where your body does not press against the ground, and a unique pattern in the pressure point areas. This allows your bag to stay lofted, and not compress all of the insulation out of your bag. It really did work, and I noticed no cold spots as I slept.
The comfort of this pad was very good. Keep in mind I have a torn hamstring, a bad back, and a torn rotator cuff, even with all of these injuries I stayed comfortable on this pad, and did not feel like I was pressing against the ground. WOW!

The pad is an absolute dream to pack, it ends up being about the size of a coke can when fully rolled up, and can fit anywhere in your pack. The pad weighs far less than any other pad on the market, making it a great choice for light weight back packing.

I am a very very picking sleeping pad person, and find very few pads that really allow me to have a good night sleep. I found the Klymit to be in the same ball park, comfort and warmth wise as the Big Agnes Insulation Air Core, and the Thermarest NeoAir.

The Klymit did have a couple of distinct advantages over the other pads:
-It is so much smaller and more lite weight
-It blows up in about 4 breaths.

This is an Editors Choice, and we consider it a BUY.

Well done Klymit!
