I'm planning to make a under quilt for the hammock, and have a question about Thinsulate. The company selling it is selling them by the width, does this mean I do not have to create baffles and just layer the Thinsulate between the shells as if it was Insulex?

Secondly, how do I calculate a temperature rating? There formulas on the hammockforum to calculating loft and down for temperature rating and I asked the same question on that forum, but no one has an answer, yet.
