A closer look
This updated sleeping mat is warmer, lighter, and thicker than the previous model, which is why the XTherm NXT MAX cements the legacy of being the go-to sleeping pad for alpinists, mountaineers, and extreme cold expeditions.

At 3-inches thick, with horizontal baffles and the added sleep surface of the rectangular shape, all-night comfort and support are at hand, 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 in frigid weather when the gloves are not coming off. When you absolutely need to be warm no matter the weather, want plenty of sleep surface, but space in the pack is at a premium, there is no finer sleeping pad than the XTherm NXT MAX.
