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. And now, the XTherm™ MAX delivers all the great features and benefits of the original XTherm in a full rectangular shape, providing added coverage and warmth for extreme temps and wider torsos. Stuff sack and repair kit included.
Triangular Core Matrix™:
- 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.
- NEW – XTherm MAX – All the performance of the original XTherm with added coverage for extreme temps and larger torsos.
The advanced design uses patent-pending technology to minimize heat loss with two stacked layers of triangular baffles, creating hundreds of individual cells in Therm-a-Rest warmest mattresses. Simultaneously this internal structure adds an unmatched level of stability to every NeoAir mattress.
ThermaCapture Radiant Heat Technology is a proprietary reflective coating that we apply to a range of surfaces. By reflecting radiant heat back to your body that is otherwise lost, this extremely lightweight coating turns that surface into a very efficient heat reflector, amplifying warmth without the excess weight or bulk of added, conventional insulating materials.
