i was wondering i have a no sew plug and was thinking about having some extra insulation on hand to slip between in case of need. been looking at both Insultex and insul bright, not sure what would work better. i will not be sewing it at all due to lack of a thread injector. my concerns are how well they pack down, and durability and warmth. they run about the same price per yd. i'm planning on getting enough for a couple layers of it for more adaptability.
any advice would be apperciated.
