Ultralight, packable three-season comfort with fast & easy inflation/deflation.

The NeoAir® XLite MAX SV mattress offers superior 3-season warmth and packability with the convenience of our new SpeedValve design. Using simple physics, the special valve allows you to inflate your insulated mattress twice as fast as traditional valves, with a fraction of the effort. See how fast you'll feel at home in the backcountry with the comfort, warmth and stability of the mattress's patent-pending Triangular Core Matrix construction and reflective ThermaCapture Barrier technology. And when it's time to hit the trail, the patent-pending, auto-reversing valve deflates the ultralight mattress almost instantly. Stuff sack and repair kit included. Learn more about SpeedValve technology at thermarest-speedvalve.com
