Therm-a-Rest ProLite Plus

Product Details 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. Four-Season Warmth: Thick, patent-pending Diagonally Die-cut Foams Pioneered by Therm-a-Rest, this technology works on the same principal as our vertically die-cut foams, lowering overall mattress density to reduce weight and increase packability. However, cut at an angle, these die-cuts decrease the direct, vertical flow of air between the ground and the top of the mattress, resulting in warmer mattress with similar weight and compressibility benefits.
