Thanks for the replies. I know about the additional cover you can add to these hammocks for cold weather but since I had a thermarest, I thought I would be fine without it... and I was in some respect when I didn't move too much. My guess is that I should get those sleeping bags with straps to maintain the mattress underneat or those quilts with a bag for the mattress. But that would mean more $ to invest... i guess I could make my own straps too.

As for supcom comments, I agree that a hammock is a weight saving gizmo but I also find that it is much more comfortable than a tent. A tarp was not an option last night since the ground was made of a mix of mud, ice and snow... and I can imagine other circumstances when a tarp would pose some problem (e.g. high wind).

Maybe it was just a bit too early... maybe I just need more practice...
