A flotation assembly designed to keep an individual afloat in water comprising a size adjustable harness adapted to fit the torso of an individual, to which are attached bottle closure devices. The closure devices are designed to have empty bottles inserted therein so as to form a substantially water-tight seal. The number of attached closure devices, and the size of the bottles inserted therein are chosen so that the degree of buoyancy desired is obtained, given the size of the individual and the purpose for which the buoyancy is required. Different types of closure devices are disclosed.
