ThermaCapture™ Radiant Heat Technology – ThermaCapture Radiant Heat Technology is a proprietary reflective coating that Therm-a-Rest 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.

Triangular Core Matrix™ – Therm-a-Rest's most advanced design uses patent-pending technology to minimize heat loss with two stacked layers of triangular baffles, creating hundreds of individual cells in their warmest mattress. Simultaneously this internal structure adds an unmatched level of stability to every NeoAir Mattress.
