I have a grey silnylon weather cover fitted for a WBBB with omnitape velcro tabs to attach to each end and every corner. I acquired it thru a hammock purchase here recently and do not foresee myself ever using it. It's very nice and looks to have never been used. $7 to cover shipping and Paypal fees and it's yours. I don't have a stuff sack for it but I'll stick it in a ZipLoc. It packs down to the size of a baseball, maybe smaller.
I'm sure he won't mind, I acquired it from Kanguru. I'm not sure who made it.
