Guys thanks for all the great post and pictures.
So here is my plan, let me know what you think. I plan on buying this sleeping bag. (see bellow). It is a 40 degree bag, 65" wide. cutting it in half the long way and using the top part is an top quilt and spraying the bottom with some water replent spray and some suspension to work with the BMBH and using it as a bottom quilt. I guess it would be two pieces at only 32.5" wide. Granted this would be for summer camping, but for under 60 dollars to have both would be a great deal.....if it works. What do you guys think? ... is it crazy?
I also thought of sewing on a velcro strip when cutting it so I can push it back together to use as a normal sleep bag if I wanted to on occasion.
