Two Young Girls Outside On The Hammock Sling

Naval hammocks are usually made from canvas or strong cotton. They are intended to be durable and stand well the hardships of the shipboard use. They usually are simple and undecorated but robust.
Venezuelan or Jungle hammocks made today are generally of breathable nylon or polyester, and use dacron or similar non-stretch suspension lines. They are 'inline' hammocks; like the canvas naval hammocks of old, the occupant sleeps along the length of the hammock, rather than across it. With their breathable false bottoms, drip strings, sandfly netting, and optional rainfly, they are one of the most secure hammocks against not only water entry, but also insect stings or bites.
Travel or camping hammocks are popular among Leave No Trace and Ultra Light campers, hikers, and sailing enthusiasts for their reduced impact on the environment and their lightness and lack of bulk compared to tents. They are made of sturdy nylon fabric, some feature a mosquito net and storage pockets. Some types offer a ridgeline to make set up easier, and may also include a slit for entry through the bottom of the hammock. Special webbing straps (called "treehuggers") are used to loop around trees in order to create attachment points for the hammock.
