I think it's the mats not the hammock that causes so much condensation. Either that or you wet the bed without knowing it. When I used to use a mat in my DD Travel Hammock, I used to find the condensation to be a bit of a problem. Now I use the underblanket and my sleeping bag as a quilt over the top of me I can regulate my temperature so easily that sweating/condensation is just not an issue.
