So these seem to be the three suggested methods to store down sleeping bags. Which is best and why?
I currently have a closet devoted to all my gear, and in there I have the four sleeping bags I own (two down and two synth) just spread out flat on the floor, kinda overlapping each other. They seem alright, but my one down bag came with a cotton storage bag, and it not only feels like a waste not to use it, but both the REI and Marmot sites say to store in bags or hang.
Thanks in advance :)
