I live in S.W. VA (which usually means high humidity and high/medium night time temps) and have a HH ULTRALITE BACKPACKER A-SYM. Now that the temps are on the rise, I am looking for an affordable---probably synthetic fill for ease of washing---summer sleeping bag or under quilt. Having looked at both the commercially produced under quilts (too expensive) and the DIY quilts (sorry, I can't sew & also do not have a sewing machine); I have not been able to find what I want.
Would appreciate any suggestions, plus pictures............especially those based upon personal experience/use in the HH ULTRALITE BACKPACKER A-SYM.
