Quick Overview

With cutting edge Triangular Core Matrix™ construction and ThermaCapture™ technology, the XTherm NXT delivers a 7.3 R-value while weighing just 440g (15.5 oz) in the Regular size. Put another way, the best warmth-to-weight ratio of any sleeping pad ever created.

It is warmer 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 are at hand, while 70D nylon on the bottom ensures the XTherm NXT holds up to extended expedition use.
