With cutting-edge Triangular Core Matrix construction and ThermaCapture technology, XTherm NXT offers an R-value of 7.3 while weighing just 439g (15.5oz) in regular size. In other words, the best warmth-to-weight ratio of any pad ever created.

It's warmer, lighter and thicker than its predecessor, which is why the XTherm NXT solidifies the legacy of being the go-to sleeping pad for mountaineers, mountaineers and expeditions in extreme cold conditions.
At 3” thick, with horizontal baffles, all night comfort and support are at your fingertips, while 70D nylon on the bottom ensures the XTherm NXT will stand up to extended expedition use.
The WingLock valve allows for quick inflation and deflation, but is also intuitive and easy to use in cold weather conditions when the gloves don't take off.

Mattress tested following the procedures set out in the EN ISO 11-092:2014 standard at an independent textile research institute The thermal resistance test is the measure of a product's ability to protect against the cold. The mat is placed on an electrically heated plate: the lower the energy needed to keep the temperature constant, the greater the isolation. A higher value of the R R-Value coefficient corresponds to better insulation
