For the first time in my life, I had a good light sleep in the woods. Usually on my Thermarest, I need to change positions several times per night due to soreness. Not on the Big Agnes REM Core Sleeping Pad. With its two and half inches of padding, I sleep comfortably. It also packs so small that I can carry a smaller pack. And I am saving over a pound in weight over my full length Thermarest. There is one drawback to this pad - no insulation. So when I am packing into snowy areas or places where the ground has recently been frozen, I bring a full length half-inch foam pad. Then I get three full inches of padding for only around two pounds.
