Therm-a-Rest Neo-Air Xtherm Sleeping Pad
Patent-pending, reflective ThermaCapture technology traps radiant heat while Triangular Core Matrix construction minimizes convective heat loss-all without the bulk, weight or durability issues of down and synthetic fills.
2.5" (6 cm)-thickness and baffled internal structure provide unrivaled stability and support.
Free of bulky, conventional insulating materials, the XTherm mattress packs to the size of a one-liter water bottle.
Advanced materials and a tapered design reduce weight without compromising warmth.
R-Value of 5.7
The XTherm air mattress delivers, by far, the greatest warmth-to-weight ratio available in any air mattress, allowing you to go lighter than ever in winter conditions. Patent-pending ThermaCapture Radiant Heat Technology gives the XTherm air mattress true four-season warmth without the weight or bulk usually found in a winter-worthy mattress. The result is a mattress that weighs less than a pound, takes up about the same space as your water bottle, and provides serious comfort in extremely cold conditions. Pump sack and repair kit included.
