I never considered using mine. It was a gift and I used it twice for, dare I say......tent camping. It's an excellent system, but I did get a bit of CBS on an air mattress. Those things suck the heat out of you anyway and it was around 25 deg both nights. For the weight penalty alone, I would not even think of taking it hammock camping. Unless you're car camping. It's pretty "fluffy" too. I'd think it might be uncomfortable in a hammock. You could always use part of it for an underquilt and the rest as a TQ.
