Designed for mountaineering, alpine adventures and cold weather camping, the award-winning Therm-a-Rest NeoAir XTherm NXT Sleeping Mat combines ultralight packability and serious comfort. Thanks to its best-in-class warmth-to-weight ratio, it’s built for the coldest nights, while tipping the scales at only 570g in the large size. With a chill-fighting 7.3 R-Value and the Triangular Core Matrix construction - a dual layer of bonded triangular baffles - it retains warmth and maintains a consistent loft from head to toe. This ensures stable, comfortable support even if you shift during the night, without the weight or bulk of heavy winter sleeping pads. ThermaCapture technology works harmoniously with the Triangular Core Matrix to encourage toasty warmth. This ultra-lightweight reflective film is carefully positioned to prevent loss of radiant heat, targeting it towards your body as you settle down for a quality night’s sleep. With a 7.6cm (3 inch) thick profile, this sleeping mat provides a protective barrier to shield against cold grounds, boosting the warmth and thickness compared to earlier designs. The tough base of durable 70D nylon withstands rough alpine terrain, while the top uses lightweight 30D ripstop nylon for comfort and minimal pack-down size. Inflating is hassle-free even in gloved hands via the one-way WingLock valve. It prevents air from escaping during inflation, and delivers fast deflation when it’s time to pack up for your next destination. The WingLock valve also makes it easy to customise the level of inflation just-right to suit your sleep preferences - whether you sleep better on a firmer or more cushioned sleeping pad. The Therm-A-Rest NeoAir XTherm NXT includes a pump sack, stuff sack and field repair kit, ensuring this addition to your sleep system is adventure-ready. 

Key Features: 

  • Exceptional Warmth-To-Weight Ratio: At just 570g in the large size, you get reliable warmth for winter camping, high-altitudes and cold climates, without non-essential weight.

  • ThermaCapture Technology: Reflective interior layer captures and retains radiant heat to maximise overnight warmth.

  • Lightweight 30D Ripstop Nylon On Top: Lightweight comfort with a smooth next-to-skin feel and easy packability.
