Seems Cecile and I cannot help ourselves where a fabric bargain is concerned. We have just met the old designer for Rip Curl ski suits [ The Alps 3000 series] and have come home with most of a roll of 85GSM Thinsulate
Naturally I have lost all the data that 3-M sent me
But because this is scrimmed on both sides it should be very easy to work with and I'm wondering about another sleeping bag overbag and not getting the OP Cocoon.
So the question is has anybody ever heard about the use of the scrimmed insulation without any shell fabric?
I'd be using the Goretex bivvy on the outside so putting a shell fabric on the outside seems a little redundant
So how warm would a couple or three layers of this be>?
