Free Shipping! (USA)
The ThermARest XTherm™ Air Mattress delivers the greatest warmth-to-weight ratio available in any air mattress by far, with a softer, textured no-slip fabric for better next-to-skin comfort and a quieter rest. Multiple, reflective ThermaCapture™ layers give the XTherm™ Air Mattress true four-season warmth without the weight or bulk usually found in a winter-worthy mattress. Stuff sack and repair kit included.
Unmatched Warmth-to-Weight: 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.
Excellent Comfort: 2.5” (6 cm)-thickness, soft-touch fabrics and baffled internal structure provide unrivaled stability and support.
Highly Packable: Free of bulky, conventional insulating materials, the XTherm™ mattress packs to the size of a one-liter water bottle.
Ultralight: Advanced materials and a tapered design reduce weight without compromising warmth.
