Got a hypothetical insulation question for you. Lets say I have a down bag, say 30 degree rated. It's a mummy bag and it has a thickness (when used as a mummy bag) of 2" of down on top of me. (this is hypothetical by the way).
If I were to use the same bag as a quilt on top of me, would the down pile up differently because of the sides of the hammock making the layer thicker and increasing the thickness of down, thus the temperature rating?
