The Evolite Plus combines ultralight, high-loft comfort and compactness with the convenience and support of self-inflating foam. 

Thermarest says:

If you’re looking for the best value in ultralight, backpacking mattress comfort and convenience, look no further.

The EvoLite Plus mattress’s patent-pending AirFrame construction is the foundation, using alternating channels of foam and air to combine amazing compressibility with easy self-inflation and a stable, high-loft comfort not found in most air mattresses.

In addition, this is our first self-inflating mattress to utilize our patent pending reflective ThermaCapture technology inside – yet another Therm-a-Rest first – boosting warmth with virtually no added weight or bulk. It delivers all of that while remaining light enough to satisfy anyone looking to move with a minimum through the backcountry. Stuffsack included.

Air Frame Construction

Air Frame Construction is really quite simple. It uses alternating channels of foam and air to create a skeleton of foam within an air mattress. The resulting hybrid of technologies offers the best of both - the high-loft comfort and compressibility of an air mattress, and the convenience, added stability and support of a self-inflating mattress

Thermal Foams

Thermal Foam is our proprietary, solid-core foam. While it may look like just foam, we have spent decades working closely with our supplier, evolving this most basic element of our self-inflating pads. The resulting foam is made in the USA, and optimized for the best balance of light weight, lasting durability, and uniformity of support.

The Evolite Plus is the latest addition to Thermarest's Fast and Light series and is a warmer version of their current Evolite mattress. It utilises Thermarest's reflective ThermaCapture technology inside, which traps radiant heat and boosts warmth, creating a warm mattress with virtually no added weight or bulk. 

And while it remains a lightweight option, at 6.3cm thick, it provides all the comfort you would expect from a mattress. It's constructed using the same AirFrame construction as the Evolite, using alternating channels of foam and air, intended to combine compressibility with self inflation.
