Thanks to its innovative Triangular Core Matrix construction and ThermaCapture technology, the XTherm NXT generates an R-value of 7.3 at a weight of just 439 g (regular size). This mat is warmer, lighter and thicker than the previous model, which is why the XTherm NXT is the first choice for mountain professionals, mountaineers and expeditions in extreme cold. Thanks to a thickness of 7.6 cm and horizontal chambers, this mat is particularly comfortable and offers good support. The 70D nylon underside ensures that the XTherm NXT can withstand longer periods of use. The WingLock valve ensures fast inflation and deflation. It is intuitively designed and can also be used with gloves.
