I bought this for some tropical camping and it is nice. Temps at night were in the mid 70's so this worked perfect. I bought the double so I could wrap it around myself twice. It works perfect in the place of a sleeping bag for warm weather camping and packs down to the size of a 16oz can. One other added feature I have not read anywhere else. Let's say you spend a little too much time in the sun and get a nice burn, well silk feels really nice on burned skin. Cotton feels itchy and lets you know every time you roll over that you have been burned. I was surprised to find sleeping with a little burn could be comfortable.
