Rectangular mat that is warmer, lighter and thicker than previous XTherm models. Made of two stacked layers of trangular baffles for stability plus an internal reflective coating to reflect your heat back to you this mat boasts a 7.3 R-value and 3 inches of cozy thickness. The mat has 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. At only 650 - 680 grams this is the warmest, most comfortable mat you can get in this weight range.

Comes with pump sack, stuff sack and repair kit.
