I don't know if this is a new idea or not, but I have put a twist on the Blackbishop bag idea. I keep my Whoopieslings and straps permanently attached. I run my adjustable loop end through a sewn loop in the strap, then I just attach it as usual over the MSH. Anyway, since I keep everything together, I wanted a way to segregate the hammock from the straps in case I have tree sap on them. For that I have made a double ended stuff sack with drawstrings on each end.
On one end, I sewed grosgrain across for extra strength and sewed each side together with a small gap in the center just big enough to run my Amsteel loop through. This runs into the storage pocket for one end of my suspension. On the other end, I sewed grosgrain again, but formed a channel through which I run shock cord. The slight compression of the shock cord helps keep the hammock in the main compartment as I am stuffing it back into the bag. I then have a pocket for the suspension on that end. The bag stays attached, and can be used as storage while the hammock is hanging. I have not weighed the bag alone, but it has to be only a few oz. It is made from polyurethane coated ripstop at 22"x24", less than 4 feet of grosgrain, about 4 ft of paracord and two cord locks.
I have made one before without the shock channel, and it worked very well. I hope ya'll like the idea!
