User Review: Exped DownMat 9

I bought this mat about a year ago and so far it has performed admirably. The built-in pump is vastly superior to the 2-way valve used on self-inflating mats, though it does take a pretty long time to inflate. When inside a tent, it can be a bit difficult to use depending on space. 

This mat packs down smaller than any self inflating mattress I have ever owned or seen. The stuff-sack is large enough that even with a little bit of air inside, it still fits nicely. 

Even having been used in temperatures around -25° Celsius, the Exped manages to keep the bottom of your sleeping bag warm and comfortable. Having said that, the mattress is very loud if you move around in your sleep. This seems like a fairly minor thing, but if you are a light sleeper, the scraping between mattress and sleeping bag could wake you up.
