I found some threads on this suff, but nothing recent.
I picked up some of this Insul-Bright yesterday, to make a sleeping bag pad, to use inside the bag.
I have the top cover cut from fleece, but havevn't decided on the bottom cover.
I am thinking to layer it as:
undecided so far.
I am hoping to use it as a pad inside the sleeping bag. 24" by 72"
The threads I found go back as far as 2007 and a few in 09.
