I did not whether to put this under top insulation, bottom insulation, pads or whatever; but I did find this link
It has a clo value of 11.6, retains 97% of its insulation when compressed under 15 psi.
The site reminds me of Insultex (which I was researching when I found this) but with more insulation. It has applications in footbeds, outwear and sleeping pads.
I just thought I'd see if anyone has seen this in person or has any more information on it.
