I've never had luck carrying coban in an aidbag for long periods of time. It always seems to get squished unless I keep it in a hard shell of some kind. I generally don't use it for TC3 type care, so it stays in my larger kit on a platform and gets largely ignored. Right now I have a behemoth aidbag that I use for medical coverage and I try to keep a few rolls at a time in a ready access boo-boo pouch. I end up going through about a roll per week, so it all stays pretty fresh. I haven't had a space concern but I'm intrigued to know if unrolling and re-rolling it will work.
