Hey Paul, any chance you could make up an under cover weather shield in the future? I tried my BBO top cover on the bottom but didn't thread the shelf/netting through the slots and instead pulled them over the top of the BBO. I think it might work ok as a bottom shield but I am not sure if it might tension out a bit too tight and compress the under quilt when laying in the hammock. Here are a few pics of my BBO on the bottom. If you could make a weather shield similar to the BBO but a bit looser fitting, without the velcro slots for the netting, but keeping the elastic along the sides to keep it held up along the sides better you'd have a winner and I'd be first in line to buy one. I'd make my own but I don't have a sewing machine. I currently use a dry ducks poncho but I don't really like taking it because it doesn't pack down well enough and it's too fragile. Just a thought.
