>>2170382warbonnet makes good underquilts but I myself have a Snugpack Chinesium underquilt and other than adding 4 mini carabeaner's to hitch it to my hammock it has been amazing and I have not had a cold night yet in it down to 38 degrees. The issue is its bulky and weights 3 pounds but its pretty cheap and will cover you for everything but deep winter.
