I know, Ideally I'd use an Underquilt.
For my boys, it seems to be no problem at all. Climb in the hammock, squirm into the sleeping bag. They also weigh a lot less than I do, which I suspect is a huge part of my problem.
Every time I sit in the Hammock, both ends of the sleeping bag slides downhill toward where I'm sitting, and makes a giant wad, making it nearly impossible to get it flattened out again, and get me into the bag and zipped up. Last night, after 20 minutes of tossing and turning inside the hammock, I gave up, and just laid on top of the wadded up mess.
Any suggestions would be helpful.
(FYI: Hennessee Hammock, if it matters...)
