The NeoAir XTherm NXT from Therm-a-Rest is the warmest NeoAir model from Therm-a-Rest. The sleeping mat impresses with an excellent warmth-to-weight ratio and has a small packing size. The five beds of ThermaCapture technology and the Triangular Core Matrix construction generate even more warmth and make the NeoAir XTherm NXT a fully-fledged all-season sleeping mat with an R-value of 7.3. With the Triangular Core Matrix construction, the dividing rods are arranged in such a way that a double-layered chamber system is created in a triangular shape. These chambers not only reduce the exchange of air between the top and bottom, but also serve as a supporting element. Considering its low weight, the NeoAir XTherm NXT is extremely hard-wearing and tear-resistant. It can also be packed very small and fits into any backpack. A pump bag, packsack and repair kit are also included. Mountain sports enthusiasts, hikers and campers agree (maybe soon you too?): There is hardly a better choice for minimum weight and maximum warmth.
