I'm a little bit overwhelmed while looking around for sleep systems for my hammock. I was wondering if maybe some of you can give me some tips. I want to do some extended traveling and will be using my hammock frequently. I don't intend to be staying in any places below freezing. My main aim is light weight/little bulk. What is going to be the lightest and most effective? I was looking at some of the enLIGHTened TQ's. Would these basically require that I use a sleeping pad along with it?
