This product is sold out

More warmth per gram than any other air mattress in the world.

The 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 ThermaCature 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.

 Regular: 12 oz

20 x 72in 



  • Unmatched Warmth-to-Weight: Patent-pending, reflective Thermacature technology traps radiant heat while construction minimizes convective heat loss–all without the bulk, weight or durability issues of down and synthetic fills.
  • Excellent Comfort: 2.5 in (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.
