I posted this question on another thread but thought it might be worth its own separate thread.
I'm about to start making 3 sew-up PLUQs for my daughters and a friend's son. I bought the poncho liners off of fleabay and they seem a bit thinner than the one I bought last spring in a local army surplus shack. With that in mind, I want to add an extra layer of insulation for a bit of extra warmth. My intent is to sandwich the insulation between the layers of the PLUQ.
In the other thread Insul-Brite and Insul-Fleece were discussed. Since both of those materials appear to be an aluminized mylar with a fleecy coating I'm a bit concerned about their durability, not so much when in use but when they're folded, rolled or just stuffed into a stuff sack. Durability probably wouldn't be all that big of a deal is I were making a No-Sew PLUQ and had the ability to change out the insulation relatively easily but since I'm making a sew-up version, I'd like an insulation that I won't have to be too concerned atour it pulling loose inside the PLUQ or simply disentigrating.
I know there are other great insulation materials out there like Thinsulate, Primaloft, climashield and even Insultex. However I'm looking for something thatcan be sourced locally (as in at a Hancocks or Joann's) that I don't have to order.
