Therm-a-Rest's XLite mats offer great pack size and weight with unbeatable insulative properties.

Thermarest says: The NeoAir XLite mattress delivers more warmth and comfort per ounce than any other three-season air mattress available. Our patent-pending technologies deliver that performance with minimal weight and less bulk than a one-liter water bottle.

This year, new softer fabrics bring better next-to-skin comfort and a boost in durability, all with no added weight. For the discerning alpinist, thru-hiker or backcountry minimalist who’s counting every ounce, there is simply no better choice to assure the kind of rest you need to get done what you’ve got planned for tomorrow.

Triangular Core Matrix

Our most advanced design uses patent-pending technology to minimize heat loss with two stacked layers of triangular baffles, creating hundreds of individual cells in our warmest mattresses. Simultaneously this internal structure adds an unmatched level of stability to every NeoAir mattress.


ThermaCapture Radiant Heat Technology is a proprietary reflective coating that we apply to a range of surfaces. By reflecting radiant heat back to your body that is otherwise lost, this extremely lightweight coating turns that surface into a very efficient heat reflector, amplifying warmth without the excess weight or bulk of added, conventional insulating materials.

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.

Small and light but you can roll off!

I have used this 3/4 length airbed on snow as well as in more benign conditions with my legs below the airbed resting on my rucksack. In combination with a winter sleeping bag I was warm and cosy, sleeping well. The only issue I found was that once or twice each night I rolled off it, maybe as it shifted sideways, and woke up on the cold groundsheet. This was despite my tent being small and being surrouded by bits and pieces. The inclusion of a repair kit with the airbed was a bit worrying but it has not leaked yet....

Classic piece

An Ultralight staple, the famous XLite. When fully inflated it is quite comfortable. Forget the complaint about noise you tend to hear a lot about this product. It never bothered me enough not to sleep, and after a few uses it goes away. Notice however, it is narrow and tapered, so your arms might have trouble staying on top. The valve is secure, it regulates your inflation breath. It takes about 6-7 good breaths for maxing out. Pack down volume is very small. The downside of this mat I would say is the not so great warmth. Personally I found it too cold for temperatures below 7-8 deg Celsius. My back was getting slight chills. I might have to use my jacket for these temps. However, I use a very light bivy and thin groundsheet, and sleep on wet ground. If you are in a dry place and use a 30D groundsheet you might be able to go to 2-5 C with this is I suspect. But I do not think it is suitable for 0 C. An air mat R rating depends on more factors than a foam mat. So you might get slightly less warmth than the specs. Overall 4/5. Comfort 4/5 Weight/Volume 5/5 Warmth 3.5/5
