The Therm-a-Rest EvoLite Mattress is a self-inflating air mattress for hours of shut-eye while exploring the backcountry. The EvoLite blends the convenience of self-inflating foam pads with the comfort of an air mattress, all in the name of a good night's rest. The two inch height is ready for three season backpacking, with a 2.1 R-value. The Atmos™ Foam provides support while a couple extra breaths of air from your own lung power adds in the firmness you prefer. The regular length comes in at 1lb, 1oz and packs into the included stuff sack for easy travel from camp to camp.
