POCKET-SIZED HAMMOCK - this frameless mini-hammock, woven from tough nylon, rolls up into a fist-size ball and slips easily into a pocket. It is equally useful for boating or camping. Suitable for persons up to 6'3" tall.
When Christopher Columbus spotted Carribean Indians sleeping in cotton nets slung between trees he thought it was such a good idea he adopted it for his crew. By 1660 hammocks were widely used in ships and sailors sometimes had to share a double one. The name, hammock, is derived from the Spanish word hamaca. Wise old sailors still prefer to sleep in hammocks, even onshore, because they get a good night's (or day's) rest.
