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.

Thermarest says: The XTherm air mattress delivers the greatest warmth-to-weight ratio available in any air mattress by far, with a new, softer, textured no-slip fabric for better next-to-skin comfort and a quieter rest.

Multiple, reflective ThermaCapture layers give the XTherm air mattress true four-season warmth without the weight or bulk usually found in a winter-worthy mattress.

Stuff sack and repair kit included.

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.  

We've tabled the five models of NeoAir mats below, along with the Evolite Hybrid mat, so you can make a high level comparison.
