Abstract
A waterproof enclosure includes a pliable, waterproof, elongated sheath having either a closed end and an open end, or two open ends; and a resilient, waterproof, sealing element associated with each open end. A pliable, waterproof, bellows can be interposed between and contiguous with the end of each sealing element and the sheath. Each sealing element may include a first end that is of smaller diameter than a second end, a frustroconical shape, and ribs. A closed sheath end may have a rough surface to improve traction. A gas passage through the sheath can be provided that includes a port actuatable from a first state for inhibiting gas movement through the gas passage and a second state for permitting gas movement through the gas passage. The port can be manually movable from the first state to the second state, and it can include a pressure relief valve. The waterproof enclosure can include a loop integral with the exterior surface of the sheath to which an elasticized cord may be attached. An apertured covering that encloses at least a portion of the waterproof enclosure is also disclosed.
