Thermarest ProLite Plus Self-Inflating Mattress


* Required Fields


The Thermarest Prolite Plus is a superb self inflating mattress providing 3 season insulation along with excellent comfort. A combination that make the Prolite Plus one of our most popular self-inflating mattresses as it offers enough warmth for cooler weather camping but is light enough for expeditions, trekking and backpacking use.

The Atmos urethane foam has holes cut into it to lower the overall density and weight of the Prolite Plus. In this latest version of the mat theses are cut at an angle. This has the effect of decreasing the air flow between the ground and the top of the mattress but still keeping the weight to a minimum along with excellent ability to be compressed. The outer 50 denier Polyester fabrics are tough and durable with the addition of Rip-stop on the upper side.

The ProLite Plus mattress combines outstanding all-season warmth with the convenience of self-inflation. U.S. sourced patent-pending diagonal-cut foam delivers more warmth than the more common vertical channels, making it the ideal choice for ski touring, cold weather expeditions and winter camping. Stuff sack included.
