Get something under you, pad, quilt, fleece, something. You can't make it on just hammock fabric unless you are the rare breed that can sleep on a slab of ice and be fine.

My first trail trip did NOT go well but I have learned and as time goes on I have made some refinements and I'm doing great now and loving my hammock. You can't read enough to figure it all out, you just have to try it and learn.
