You can also use a foam pad under you in a hammock but I find it to be uncomfortable having *anything* underneath me in a hammock. So this is why I also no longer use my sleeping bag + pad in a hammock, it was a nightmare gettng in and out of it, constantly squirming about trying to get it in just the right position. I can't even begin to tell you how much more comfortable it is having nothing between you and the hammock, a TQ/UQ setup is expensive but far superior in terms of warmth and comfort.
