medicine man, no zippers? true enough but neither does a speer hammock (velcro), and my home made one doesn't have velcro or a zipper. and seals fine when a body is in the hammock.

cold shoulder wrap is a problem, and this is why many folks use a wider pad; my wife uses a yoga mat. I gotta tell you, talk about non slip super insulation.

while I still use my single layer hammock, I am getting ready to make a double layer and be rid of all the pad issues.
