User Review: Exped DownMat 7
Price Paid: $150
I was very impressed with the Downmat 7 and had used it on several extended ski mountaineering trips. The insulation worked very well preventing heat loss when sleeping on snow which was the whole point.
My friends were using Thermarests supplemented with closed cell pads (thinsulite), carrying two sleeping pads seemed to ad a fair amount of bulk, however weight was not significantly more.
Only one problem Downmat only works if inflated and if the valve fails (twice now, both times replaced by d/m) you are going to be sleepless until you get home. I could not figure out a way to repair or rig the broken valves in the field.
