Therm a Rest Trail Pro (2014) Self Inflating Sleeping Pad

Updated for 2014! Combining lightweight construction, rugged durability and a comfortable 2 inch thickness, the Therm a Rest Trail Pro self inflating mattress offers versatility for backpacking, camping or general travel.Providing an R value of 4.0, the Trail Pro's expandable foam core makes it suitable for year round use. The easy to use self inflating design allows you to simply unroll the pad and open the valve. The open celled foam responds by soaking up air, similar to the way in which a sponge absorbs liquid. Once the Trail Pro has had time to inflate, you can adjust firmness by manually adding or releasing air before re tightening the valve.The Trail Pro self inflating sleeping pad utilizes diagonal cut foam, which brings added warmth by minimizing convective heat loss. Pressure mapping technology provides targeted support and softness in those areas where you need it most, the shoulders, hips and knees. Strategic foam die cutting balances packed weight by reducing bulk in other areas. The Therm a Rest Trail Pro sleeping pad is available in two sizes. The Regular size measures 20 x 72 and the Large is 25 x 77. A stuff sack included aids in packability and provides water resistant protection. Large, Regular, 6422, 6421
