I have read with great interest your design idea for the DAM. I also
visited Stephenson's site and downloaded their catalog with awesome
information on their vapor barrier concepts and cold weather sleeping
systems. Interesting way to display their products!
I am assuming that your design places the DAM directly beneath you and
you put all your weight on it. Has this pressure stressed the material
that the tubes are made of? How are the multiple tubes attached together
(sorry if you already answered these, I may have missed it).
I have read other people's design ideas about using an extra bottom that
is larger than the main bottom, and placing insulating material between
them, and I am wondering if a combination of your concept and a
modification of Risk's ZHammock design with a larger second layer for the
bottom would be the answer for simplicity and reduced weight, while
preventing so much direct pressure from being applied to the DAM.
I am cutting the material for my second hammock, which will be
ZHammock-style, and I am considering making that second bottom layer a
few inches larger in all directions (by cutting the top layer smaller) to
allow for your DAM or something like it.
Anyway, thanks for sharing, very cool concept.
