The opinion of Aventure Nordique
The NeoAir XTherm is the ultra-light 4-season mattress from Thermarest! It has a thermal resistance R-Value of 6.9 with the new ASTM F3340-18 standard, making it by far the lightest 4-season mattress on the market. The NeoAir XTherm can be used down to a temperature of -20°C. It is perfect for winter bivouacs! It is the ideal ground mat for ski raiding, snowshoeing and all cold weather adventures!
This mat is the warmest of the Thermarest NeoAir range. It is equipped with the "reflective barrier" technology which is a high-performance thermal insulation system. The XTherm is composed of multi-layers forming a reflective barrier: heat is reflected towards the body and cold from the ground is blocked. This innovative system provides a real feeling of warmth. The socks have a special design that traps the warm air inside.
The NeoAir XTherm has a volume equivalent to a 1 litre bottle of water, which saves space in the backpack compared to a conventional self-inflating mattress. Its mummy shape allows this volume and weight gain.
The NeoAir XTherm is very comfortable: you sleep on 6.4 cm of air!
This Thermarest mattress is strong and puncture resistant. It is equipped with a 50 denier anti-slip reinforced nylon fabric on the bottom and a 30 denier nylon on top.
The XTherm is equipped with Thermarest's latest valve. The WingLock valve allows you to inflate and deflate faster. It has a non-return valve that prevents air from escaping during inflation. The mattress is supplied with a storage box and a pump bag that prevents blowing moisture into the Therm-A-Rest. Repair kit included.
