There is a lot of information out there but some of it seems conflicting. So I'm looking for definitive answers before I jump into making my own down topquilt. Currently, I use a synthetic bag for a topquilt. It's heavy and bulky, but there have a been a few times dealing with condensation/moisture that I was grateful that I had synthetic so it makes me nervous jumping over to down.
So my questions surround what type of coating/materials should I use to best avoid moisture issues. On one hand, if I'm thinking only about sweat, I'd think I'd want DWR on the bottom layer (by me) and non-coated breathable on top. On the other hand, to prevent moisture from my breath and condensation from getting in I'm thinking I'd want DWR on top but this limits the quilts ability to breath and let my sweat escape.
What is the final consensus? DWR on top/bottom? DWR only on bottom? Neither?
If it helps, I generally don't seem to have problems with moisture/condensation build up from my breath until it gets really cold. Right around the teens F, my bag starts getting wet around my face where my breath builds up on the material. I also have a tendency to want to pull the bag over my head a bit while sleeping which only exaggerates the problem. I do some winter camping and see temps in the teens often enough to be concerned with it.
On another thought, I've debated adding a section of light fleece at the head end that 'hopefully' would capture moisture from my breath. Seems like I've seen that on some manufacturers quilt and it looked like a good idea. Any thoughts on if that's functional? I've thought about only attaching the fleece at one edge so it could flop over my head.
