Hello everyone, I am have a bit of a dilemma right now. I am going to make my own DIY under quilt, but I don't know what material to use for the insulation. I want it to be able to go down to around 20-30F. I also want it to be fairly compressible so that it isn't taking up all the space in my pack. As of right now I am leaning towards Primaloft One, but I am open to suggestions. However, I do not want to use down or Insultex.
