Tried this in a single layer last night here in NJ. Sleeping bag worn as such (not quilt style). Got me down to below 55 before CBS set in and I went inside at about 5 when the temp had dipped below 50. Having trouble with initial placement (it seems to float around as hammock is entered--see other thread).

Otherwise quite impressive for a 1/16th inch product. I will try a double layer tonight.
