Klymit Inertia X Frame Sleeping Pad

Originally published 2012

From the archive: originally posted in 2012, shortly after the Inertia X Frame launched. Klymit's range has expanded since, but the body-mapped design is still around.
Klymit Inertia X Frame sleeping pad body-mapped shape

Generally in the camping gear market we see a lot of evolution but not much revolution. Until now. Klymit have completely turned sleeping mats on their head with the Inertia X Frame. This is an inflatable sleeping mat but without the unnecessary material, which makes it extremely lightweight with a tiny pack size.

As the body-mapped shape shows, there's padding for shoulders, head and hips, but unnecessary padding is removed. This makes the sleeping mat super light at just 9.1oz — only 258 grams. It also rolls up to the size of a coke can, so this is a super light and super small camping accessory. Since it does have gaps, the Inertia X Frame is only rated for 3-season use.

You can either place the sleeping mat inside your sleeping bag or below it — it's recommended you put it inside, since it's shaped for a mummy bag, and the sleeping bag fill will actually loft up through the holes allowing extra insulation.
