Conquer freezing alpine nights without sacrificing pack space! The XTherm NXT ultralight sleeping pad delivers an industry-leading 7.3 R-value—the pinnacle of warmth-to-weight efficiency for extreme expeditions—while weighing just 15.5 oz (440 g) in Regular size. Engineered for mountaineers and polar adventurers who demand reliable warmth when temperatures plummet, its revolutionary Triangular Core Matrix™ construction minimizes heat loss, and ThermaCapture™ technology reflects your body heat back to you. Experience all-night comfort on demanding trips with a plush 3-inch thickness and supportive horizontal baffles, even during multi-week treks across rugged terrain.
Durability meets ultralight design: rugged 70D nylon base fabric withstands sharp rocks and snow camps, while the top layer uses featherlight 30D ripstop nylon for minimal bulk. The intuitive WingLock™ Valve inflates rapidly (3x faster than standard valves) and deflates instantly—even with gloves on—making camp setup effortless in frigid conditions. Perfect for high-altitude climbers seeking the warmest sleeping pad for mountaineering, it includes a pump sack, repair kit, and stuff sack. Choose from Regular, Regular Wide, or Large sizes (all in Neptune blue) to optimize your sleep system. When every ounce counts but warmth is non-negotiable, trust the XTherm NXT—the ultimate cold weather sleeping pad for extreme expeditions that redefines backcountry comfort.
