The Thermarest NeoAir is the world’s lightest, most advanced 3-season air mattress available. The pinnacle of ultralight and ultra-small.

Beyond being the lightest air mattress, the NeoAir utilizes a patent-pending R2 reflective barrier to reflect heat back to your body and cold back to the ground, keeping you warmer. Patent-pending baffling creates rows of insulating cells to minimize convective cooling.

When inflated, the internal baffling Triangular Core Matrix creates an internal truss system that virtually eliminates instability. 2.5 inches thick, the NeoAir has an R-value of 2.5.

You’ll appreciate that it’s no bigger than a one-liter water bottle. Revolutionary by design, the NeoAir mattress makes comfort one less thing you’ll need to compromise when traveling Fast and Light.
