The Therm-a-Rest NeoAir mattress packs to the size of a one litre bottle and weighs only 14 ounces for a regular size, making it the perfect choice for people with strict weight and space limitations. When inflated, the NeoAir mattress is warm to sleep on, thanks to a patent-pending Reflective Barrier that reflects heat back to the user’s body and reduces convective heat loss to the ground.
A second patent pending technology, the Triangular Core Matrix, contributes to the warmth by creating a multitude of air cells that minimize air movement and convective cooling. This matrix also creates an internal truss system that virtually eliminates the instability generally found on large tube-based air mattresses and assures that the user will shift less while resting comfortably on a 2.5 inch-thick mattress. Since thermal efficiency is achieved without the aid of down or fibre insulation, the NeoAir mattress can be blown up directly, without the added weight of an air pump or having to worry about exhalation moisture wetting insulation and decreasing performance.
