NeoAir XTherm NXT Large Insulated Camping Mat

About the ThermaRest NeoAir XTherm NXT Large

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 570 g (1 lb 4 oz). Put another way, this air bed gives you the best warmth-to-weight ratio of any sleeping pad ever created.

It is warmer, lighter and thicker than the previous model, which is 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 is also intuitive and easy to use on super-cold nights when the gloves are definitely not coming off. If you're after reliable overnight warmth no matter how far the mercury dips - and space in the pack is at a premium - there’s no finer sleeping pad than the XTherm NXT from ThermaRest.
