So im looking at making a UQ on the cheap for a friend who is currently using a pad for insulation. I have insulation and most all the little bits and pieces I need (gotta get some shock cord) to make a 3/4 UQ but i just realized all the fabric I was planning on using is just 1.9oz ripstop from Ripstopbytheroll. I know you have to use calendered fabric when using Down but do you have to use calendered for a synthetic UQ? I was planning on making this thing basically for free and just using what I have but I realized im not sure if regular old 1.9oz ripstop with contain the Synthetic insulation I have. Anyone on here know?
