Well I've got an HH explorer with an upgraded hex fly and the original asym fly as well. I'm thinking of taking the asym and somehow make it into an undercover effectively turning the hammock into a double layered hammock. Anybody have any thoughts or maybe even experience with this idea? Think i may have to lay out the hammock on the fly to get the exact shape and then cut/sew the edges maybe with some shock cord in there to keep it snug fit? Help appreciated Added thought, should i stitch the finished layer to the hammock leaving an opening to add padding etc or should i hang it up like an underquilt? Its a side entry HH.
