Therm-a-Rest NeoAir XTherm™ NXT MAX

The Therm-a-Rest NeoAir XTherm NXT MAX is the updated version of the winter XTherm pad, pushed to an even higher R-value of 7.3 through ThermaCapture reflective film combined with Triangular Core Matrix construction. Its rectangular Regular Wide shape (183 x 64 cm) offers more room than the tapered mummy version, and 7.6 cm of thickness gives solid clearance from frozen ground. That extra insulation and size come at 650 g. A 30D ripstop nylon top and 70D nylon bottom handle the demands of winter camping, the single WingLock valve enables fast inflation, and a pump sack ships in the box alongside a stuff sack and repair kit. The pad rates among the quieter models in its category, a welcome trait for a high-R winter pad. A limited lifetime warranty signals real confidence in the build. It suits winter treks, expeditions, and high-altitude climbs where maximum thermal comfort matters more than shaving weight against lighter-rated pads.
