Thermarest's NeoAir XTherm mats offer the best insulation for their weight, suitable for winter camping on very cold ground. They also offer real comfort and a choice of mummy and rectangular shapes.
Thermarest's NeoAir XTherm mats combine the comfort of an airbed with the insulation value required for sleeping in the coldest conditions and on snow.
When your backcountry pursuits demand extreme insulation and an ultralight packed size, alpinists and mountaineers turn to the NeoAir XTherm. The unrivaled Triangular Core Matrix offers the best warmth-to-weight ratio of any air sleeping pad construction. The construction gives the 2.5 inch (6.4 cm) thick pad superior stability, boasting the most inches of weld for maximum camp comfort. The packable pad boasts a 6.9 R-value, allowing users to take it into the most extreme conditions. Available in several sizes, including a roomy regular wide, the XTherm features the high-performance WingLock valve, allowing the pad to inflate three times faster thanks to a larger opening and one-way inflation. Like all Therm-a-Rest pads, the NeoAir XTherm is made in market to ensure quality and minimize environmental impact. The pad includes a breath-saving pump sack, compact stuff sack and field repair kit.
Therm-a-Rest's 2020 NeoAir XTherm Regular Sleeping Mat is still their most insulated airbed and it builds on the performance of the previous mats. This updated version comes with the new WingLock valve with easier one-way inflation and secure two step deflation.
Insulated airbeds offer a great combination of comfort low weight and small pack size - in many ways they are now the ideal sleeping mat. Some people however prefer self inflating mats because if their mat develops a leak there is still a piece of foam to lie on if your airbed develops a leak you have nothing. Other people find they sometimes roll off an airbed and prefer a thinner mat between them and the ground.
The lightest of the Thermarest NeoAir mats use very light fabrics which have been reported to make a `crinkle` sound as you move around on them - they are likened to sleeping on a crisp packet - my experience is that this is minimal - after using a NeoAir for a couple of years I didn`t realise it crinkled until someone pointed it out to me! Now I know - I still don`t notice it when kipping down.

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.
You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.
In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
