Thermarest NeoAir Xlite Max SV Regular (2019)

6 reviews   |  

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.

Featuring ThermaCapture technology, which is a material that reflects heat and minimises heat loss without adding extra weight or bulk. An ideal choice for alpinists and backpackers looking to save weight.

Fitted with SpeedValves (SV) which isn't your average inflation method. It uses simple physics to inflate your mattress three times faster than pads with a traditional valve as well as making your mat miles quicker to deflate.

The Speed Valve neck needs to be rolled for the correct number of times - 7 times - to achieve a perfect seal. Any less and it may lose air, this is a classic case of not reading the instructions.

Classic valve version - Stuff sack and repair kit included.


  • Ultralight 3-Season Warmth: Advanced fabrics, Therma-Capture technology and Triangular Core Matrix construction create ultralight warmth without bulk.
  • Fast Inflation: SpeedValve pulls in surrounding air to amplify your breath, inflating the mattress in half the time of traditional valves
  • Max Comfort: 2.5 inch (6cm) thickness, soft-touch fabrics and baffled internal structure provide unrivalled stability and support. Max shape provides added coverage.
  • Ultra-Packable: Low bulk materials make the mattress ultra-compact - as small as a water bottle.
  • Faster Deflation: Auto-reversing SpeedValve deflates mattress in a flash.
  • Stuff Sack and repair kit included.

Good Value and Good Quality

Not had the opportunity to use this outside yet however i have used it indoors five times and can say confidence is high. Great value for money and a very well known brand. No problem with it deflating, it's just a matter of following the instructions to the letter.
