I have an old down sleeping bag that I never use anymore, I want some how to integrate it into my sleeping system. I have been thinking about this idea for about an hour (seems a lot longer than that, haha), but I'm not sure if it will work. I want to some how put a hammock inside this sleeping bag so that the underside of the bag will act as an underquilt, and the top half will act as a top quilt. There is ample room in this bag, so I don't think room will be a problem. So my first question is, will this work. If it will, how do I integrate the hammock. I really want to make this work, but I think this is going to be more than I can handle.
