Hennessy Hammock has reinvented the conventional hammock and has four patents granted and three patents pending on its revolutionary design. The hammock has an entrance through the bottom that automatically shuts after you’re safely inside, and allows for easy entrances and exits without tipping. The hammock supports your lower back via its patented asymmetrical shape, a typical problem with conventional hammocks. In addition, the hammock has a shelter-cover to provide a wind-proof, bug-proof, and waterproof environment. The hammock is lightweight, and can also be used as a tent, or lounger.
