Warmer, lighter and thicker than previous XTherm models, the XTherm NXT boats a 7.3 R-value and 3 inches of cozy thickness. Made of two stacked layers of trangular baffles for stability and to minimize heat loss the mat also has an internal reflective coating to reflect your heat back to you. The fabric is 70D nylon on the bottom (vs 30D ripstop nylon on the top) for extra durability and the WingLock valve makes for easy one-way inflation and fast deflation. This mat is perfect for the minimalist or backpacker when you want the warmth but not the weight.

Comes with pump sack, stuff sack and repair kit.
