Let me say this is a great forum and I have found good information and answers. I am beginning a "gear making" class soon and plan on making two Red River UQ's. Question is, I got a couple of old down sleeping bags (ebay), and I am planning on just reclaiming the used down, shouldn't this be ok or is there a reason I should use/buy new down? Any/all advice will be appreciated.... I don't want to make them twice..
