The innovative Therm-a-Rest EvoLite mattress combines the convenience of self-inflation with the comfort of air in a uniquely built package that offers a full 2” of loft! A 2.1 R-value makes the EvoLite great for 3-season use, and a small packed-size makes it an easy ultralight backpacking companion.
The EvoLite mattress features Therm-a-Rest’s Airframe construction, which incorporates alternating foam and air channels to drastically reduce weight while amplifying loft. The open-celled Atmos foam used in the EvoLite is poured in an atmospherically-controlled chamber, which allows Therm-a-Rest to tout uniformity in the quality of each mattress in which it’s employed; Atmos foam is also extremely compressible. Durable face fabrics provide a textured surface that keeps you on the pad at night.
A self-inflating design allows you to simply unroll the EvoLite and open the integrated air valve. The Atmos foam responds by soaking up air, similar to a sponge absorbing liquid. Once the EvoLite has inflated, just a few breaths are needed to top off the fullness of the air chambers. If the mattress is too firm, pressing down lightly on it with the air valve open will release some air.
The Therm-a-Rest EvoLite is available in Small (20" x 47"), Regular (20" x 72") and Large (25" x 77") size options. Therm-a-Rest includes a stuff sack with every EvoLite mattress.

Real Customer Reviews
- Good, lightweight sleeping pad
Likes: Compresses down to a really small size and is pretty light to carry inside my pack. It self-inflates most of the way, and then I blow a few more breaths in to expand it the whole way, although I've found that it is more comfortable to not have it over inflated to sleep on it. This pad is not noisy like some other options. When not using it, I store it at home inflated so that the foam inside will maintain its loft better than if it were compressed all the time. That has helped it inflate pretty quickly when I'm setting up camp.
Dislikes: Not cheap, so hopefully it holds up well for many years to come!
