Therm-a-Rest ProLite™ Plus

Guide Pick ™


All-season self-inflating comfort - now with even less weight and bulk. The ProLite Plus mattress combines outstanding all-season warmth with the convenience of self-inflation. An upgrade to Therm-a-rest's exclusive Atmos™ Foam reduces weight and boosts compressibility. In addition, patent-pending diagonal channels in the foam retain 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.
