DownMat 7 Deluxe
Really great heavy-duty constuction, hardcore pad! I'm 5'11", 178lbs and the 7 is plenty of pad between myself and the floor, keeping me warm.
Spent a few minutes to understand how the stuff bag / pump works, once I did, it inflated rather quickly and holds air well. It has 2 release valves, be sure the second is closed tight before inflating.
Well worth the extra weight and price. The stuff bag / pump does in fact double as a nice pillow too.
