Re: Lightweight hammock........
Hammocks do work in the cold. In the winter, pre-wolves, I used a hammock, winter bivy sack, space blancket and down bag. I put the space blanket under my bag inside the bivy sack. Now, with the wolves, my dogs can't just sleep on the snow, so I've been sleeping in a snow cave. Mtn. Hardwares Kiva or Black Diamonds Mega Mid is the way to go without carrying a tent.
