Therm-a-Rest ThermaRest NeoAir® XTherm™ NXT Premium , Regular Neptune 11633

Insulated premium sleeping pad made for all-season comfort warmth With state-of-the-art Triangular Core Matrix construction and ThermaCapture technology, the XTherm NXT delivers a whopping 7.3 R-value despite weighing in at just 440 g 1 lb. Put another way, this air bed gives you the best warmth-to-weight ratio of any sleeping pad ever created. It warmer, lighter and thicker than the previous model, which why the XTherm NXT cements the legacy of being the go-to sleeping pad for alpinists, mountaineers and extreme cold expeditions. At 3 inches thick, with horizontal baffles, all-night comfort and support come as standard, while 70D nylon on the bottom ensures the XTherm NXT holds up to extended expedition use. The WingLock Valve allows for rapid inflation and deflation but also intuitive and easy to use on super-cold nights when the gloves are definitely not coming off. If youre after reliable overnight warmth no matter how far the mercury dips - and space in the pack at a premium - theres no finer sleeping pad than the XTherm NXT from ThermaRest.
