Thermarest Thermarest have revolutionised camp sleeping equipment over the past 40 years: they invented the self inflating air mattress concept and have continued to tweak and improve the design. Rest better, play better Thermarest have so much faith in their product that they offer a full lifetime warranty which we can tell you from personal experience they do honour with no fuss. More recently they created the unique Neoair mats which are rapidly becoming the standard for lightweight backpacking and adventure racing.

Shop Now The ultimate warmth for weight Thermarest Neoair Xtherm NXT The Thermarest NeoAir XTherm NXT is an update of the Thermarest XTherm. It is now warmer, more comfortable and quieter while still being the best choice for lightweight, cold weather alpinists, backpackers and mountaineers. The Neoair XTherm NXT has an R-Value of 7.3 which is more than that of self inflating mats weighing four times as much. This means that in terms of warmth to weight ratio, nothing comes close and the XTherm NXT is the warmest mat in Thermarest's fast & light range. It features ThermaCapture technology which is a series of baffles made from a reflective fabric providing an almost complete barrier to radiative heat loss, making it suitable for 4 season use. This, combined with a Triangular Core Matrix construction, makes the mat ultra light without being bulky to pack away. Shop Now
