I am in process of doing a PLUQ and looking for a way to make it a bit warmer. I found a product in the fabric store call Warm Windows. It was on sale so I purchased a few yards and am going to put it between the layers of the poncho liner.

This is a link to it.

Anyone try this before? Any feedback on it?
