Therm-A-Rest NeoAir XTherm Sleeping Mattress - Regular

Weight: 430 g         4 reviews
The Therm-A-Rest NeoAir XTherm is a professional-level four-season sleeping mattress, designed for those who need the ultimate level of insulation at the lowest possible weight. With an R-Value rating of 5.7 and a weight of just 430 g, the NeoAir XTherm delivers more warmth per gram than any other air mattress in the world, making it ideal for winter expeditions.

Therm-A-Rest's unique ThermaCapture technology helps to trap radiant heat within the mattress, while the Triangular Core Matrix construction minimises convective heat loss. This is all done without the bulk, weight or durability issues normally associated with winter-worthy sleeping mats.

The baffled internal structure of the XTherm Sleeping Mattress provides unrivalled stability and support. And, without the need for conventional insulating materials, the XTherm Mattress packs down to the size of a one-litre water bottle.

Updated in 2015, the NeoAir XTherm now features soft, non-slip fabrics, adding next-to-skin comfort and a quieter night's rest for a better overall sleep experience.

  Had this product for over a year now, fantastic bit of kit, was camping out early this year (2019) in a hammock in minus 3 and every time I turned on my side my back got cold, as soon as I lay on my back within seconds I could feel the heat radiate back to me warming my back. You get what you pay for and will definitely increase your ability to keep warm and comfortable.

  Dear Woodlore, you are just a wonderful website and company. The goods I purchased from you arrived safely and on time, and are very good. In relation to the Therm-A-Rest NeoAir sleeping mattress, I can share that I have just tested it so far at home and I am looking forward to testing it next week in the mountains. But it looks like a really wonderful product. It is light, but also comfortable and well insulating. It's really the best I could find given its product features. So thank you again for your service.
