A closer look
This updated sleeping mat 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 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. If reliable overnight warmth is the demand 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.
