The hammock comes with an entrance zipper. It can close sturdily ten zippers as well as two sliders. The hammock with zipper has a larger dimension and a little asymmetrical rain fly to increase the range on your head and feet. Other types of the hammock can be enhanced with a fly, only this hammock with a zipper that is increased with a suspension of a ridge line. Once you need more or less suspense on the fly, take sliding the knot only, and then move forward to the poly cord alongside the tree or such anchor. This is an amazing hammock that is durable, stable, and very strong.
