I've had my HH for awhile now and I dont really wanna drop the cash for an underquilt, so I've been looking at potential alternatives to help insulate the hammock. I've used a second sleeping bag and ive used a thermarest, but neither seem like good solutions. Has anyone tried using something as simple as a fleece blanket? I have a nice one that doesnt weigh much that seems like it could work, and if nothing else i wont get bit by skeeters through the nylon. But would that be enough to help insulate a hammock? Or is something more substantial needed to eliminate the notorious cold underside? (I use a mont bell down #5 bag).

If not a fleece blanket, what would be a cheap, light, alternative... please dont say 'space blanket' cause that sound drives me nuts.
