It's a cool idea that I think has it's place.
But to me I don't want to combine my pack or anything exposed with anything. I am always getting snaged on something while I am hiking. There is always a low branch, vine, thorn, or something that could put a hole in something like ripstop.
For this reason I don't even want to pack my gearskin with the hammock as a frame.
Is that too much to ask? Girls with frikkin' lasers on their heads?
