The opinion of Aventure Nordique

Now featuring SpeedValve technology, the MAX SV delivers performance of the original XTherm with added coverage for extreme temps and larger torsos. 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 ThermaCapture layers give the XTherm air mattress true four-season warmth without the weight or bulk usually found in a winter-worthy mattress.


  • 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: 6,3 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.
