Fabric for underquilts ?silinylon
In contemplating the ultimate UQ, and having asked some questions elsewhere about minimilizing the design, I was wondering about using silinylon as the underface of a home made quilt (and normal sleeping bag nylon on the surface under the hammock). I've found some discussion about moisture/evaporation issues, which I understand with respect to a quilt or sleeping bag over the top of you, but, with an underquilt, it doesn't make sense to me. Heat travels upwards.........why would you get condenstation on the bottom layer?
Some thoughts would be appreciated.
