I'm making a trip to Joan tonight with the wife to make my first DIY UQ. Would there be any point to making an UQ with the Insul-Bright Insulation you can buy there? I understand there are brand name insulations all over the internet, but it doesn't take a top secret process to make hollow polyester fiber insulation. Has anyone ever used this stuff? How warm did it keep you and how well does it compress? Any recommendations on what I can use instead if this is no good?
Anyone ever use Mylar Fleece?
