I'm thinking of using Thinsulate or Primaloft for my quilt rather than down. Question is, Thinsulate is sold by width, does that means I don't have to create baffles? Next question is how to calculate how much Thinsulate and/or Primaloft would give me x temperature rating.
Also, I was thinking about using reflective fabric as the inner shell to reflect my heat back to me, has anyone done this before? Is condensation an issue using this fabric for this purpose?
