Thermarest's NeoAir XLite Max SV mats are ideal for those counting every gram, as they offer stability and comfort in a compact, featherweight package. Now featuring Thermarest's SpeedValve for faster inflation and deflation.
Our game-changing SpeedValve paired with the best-selling air mattress in the world is a match made in backcountry heaven.
Triangular Core Matrix
Our most advanced design uses patent-pending technology to minimize heat loss with two stacked layers of triangular baffles, creating hundreds of individual cells in our 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.
The Therm-a-Rest NeoAir XLite Max SV mat is an ultralight air mattress that offers more warmth per ounce than any other three-season mattress. It's excellent insulation is down to the ThermaCapture technology, which is an innovative, proprietary material that reflects heat and minimizes heat loss without adding extra weight or bulk. An ideal choice for alpinists, ultralight backpackers and anyone seeking the most comfort per gram.
What makes these Thermarest mats stand out from others is the new SpeedValves (SV). The SpeedValve is a revolutionary inflation method that uses simple physics to inflate your mattress three times faster than pads with a traditional valve. When it's time to break camp, the auto-reversing valve deflates your pad instantly. It's a remarkable way of inflating your mat with negligible effort - watch the video - you'll be amazed.
The Speed Valve neck needs to be rolled for the correct number of times - 7 times - to achieve a perfect seal. From personal experience, any less and it may lose air - a classic case of user error (and not reading the instructions) when my mat deflated as it worked faultlessly after I'd read them and put the correct number of rolls in the SV.
