I'm sure this has been covered somewhere in here. But is there a way to enclose a hammock and make it weatherproof without a tarp. Some sort of pullout cover that zips around the top. I have seen somewhere, a war bonnet maybe that had a pullout cover. I just got a GrandTrunk SBUL and was curious is maybe I could mod it so I dont have to pack a tarp and tie outs. What do you think hangers?
