I purchased my first hammock this spring. I bought the Hennessy Hammock Explorer Deluxe Asym Zip. With my purchase I received complementary snake skins and the HH2O AutoMagic Water Collector and Rainfly Tensioner System. I have gone on two overnight outings since getting my hammock. I am very pleased with the hammock and I love the snake skins! I have not yet used the water collection and rainfly system. Has anybody used this system? What are your thoughts?
