Some people on this list have advocated using mylar as a vapor barrier
between the hammock and the underquilt or outside the underquilt. Mylar
would result in similar condensation problems.
I once tried an insulated mylar (similar to the truck windshield cover)
as an underquilt and found almost a teaspoon of condensation collected
at the shield's lowest point. So, I decided that, for me, a
non-breathable layer would not work. I'm had success with house-tyvek
as a way to block wind, splash-back, dog noses, and rolling fogs.

>> my thoughts on under quilts. I have modified a nanatuk down quilt by removing the foot box and turning it into an under quilt. with a shock cord in the sides and light shock cords over the strutural ridge line, in my home made cuben hammock.; it works great. I also put a very lite (.3 ) cuben sheet on the undersiode of the nanatuk to keep drafts and wind heat loss at a minnimum. . I'm wondering , why cant you make a down under quilt with a cuben bottom and a momentum top. ultra lite and keeps draftds and spindrift out.
