Product details

Thanks to the innovative Triangular Core Matrix construction and ThermaCapture technology, the XTherm NXT offers an R-value of 7.3 at a weight of just 440 g in the Regular size. In other words, it has the best warmth-to-weight ratio of any sleeping pad ever developed. It is warmer and thicker than its predecessor, making the XTherm NXT the top choice for alpinists, climbers, and extreme cold expeditions. With a thickness of 3 inches and horizontal baffles, the XTherm NXT provides comfort and support throughout the night, while the 70D nylon on the bottom ensures durability even on longer expeditions. The WingLock valve allows for quick inflation and deflation and is intuitive and easy to use even in icy weather, without having to take off your gloves. When reliable warmth is needed at night, no matter how low the mercury drops, and space in your backpack is tight, there is no better sleeping pad than the XTherm NXT.

"Every now and then I spend the night outside in winter. And so far I've always shivered through the night. Even the best sleeping bag is useless if the sleeping mat doesn't provide enough insulation. When I had to spend several nights in a row in the snow this spring, I needed a thicker mat...

  • PositiveThe best-performing sleeping pad for gram counters on the market scores highly in terms of comfort

    The current version of the Therm-a-Rest Neoair Xlight sets standards: the lower limit for frostbite is zero degrees, for hot spurs it is minus eight degrees - which no other mat that weighs just 380 grams (lying surface: 182 x 50/26 cm at the head/foot section) can achieve. It offers a somewhat firmer, less wobbly surface than models with longitudinal chambers and, with a thickness of around six centimetres,...
