Well, I ordered a dbl 1.7 wbbb hammock, so now my thoughts are turning to insulation. I'm thinking that initially I'll probably use a foam pad for underneath the hammock, but that leaves me with two questions.

Obviously I can't very well bring my bed sheets, and since I've been told sleeping bags don't work, I'm wondering what other compact alternatives are available.

Has anyone looked into using a rectangular sleeping bag liner, a bivvy sack, or just rolling up a wool blanket?

Also, do you guys use a ground tarp beneath your hammock?

My backpack has a place for my boots, so I was thinking of taking them off when I'm in the hammock.

I've been looking at sleeping bag liners at Rei, backcountry, and toasty liner
