UltraLight Mat

Mountain Boot Company  © Mountain Boot Company
For those looking to count grams and save as much weight as possible the Ultralight Mat fits the bill perfectly. The mat is constructed using a single layer of Air Sprung Cells. These operate in the same way as a pocket sprung mattress, where each cell deforms independently as the sleeping mat conforms to your body and evenly distributes the pressure across the mat.

Is the R-value of that mat really only 0.7?
That's a good question. Having looked into the range a little further, it would seem that the Ultralight is very much focussed on keeping weight to an absolute minimum (i.e. at the cost of greater insulation + warmth). As such, it'd be ideal for summer camping + trekking, but less fine if you're spending months on a glacier - it's most certainly not designed for that! If that's what you're looking for, the Ultralight Insulated, Comfort Light Insulated or even beefier Comfort Plus Insulated would be the ones to go for (R3.5, 4.2 and R5 respectively). Hope that's of help.

And where would one purchase one of these from? In the market and sure as hell can't forsee winning anything as usual.
There's three stockists listed on the product news page here: That said, the moment you buy one you know it's inevitable that you'll win...

Non insulated air mats are surprisingly poor at insulating - I've noticed even at temps around 5 or 6 degrees it can get unpleasantly cool on them. They are though ridiculously light and small. The one I reviewed is a bit heavier and bulkier, but fine to sleep on snow on I'd love one of the the uninsulated ones for summer bikepacking and the like when cold wouldn't be an issue - they are just so small, but from this time of the year onwards the insulated one is probably a better bet.
