Abstract

A personal ballistic protective device having a first layer comprised of ballistic material and a second layer comprised of buoyant material. The second layer preferably has a density sufficient to counteract a density of at least the first layer of ballistic material such that the first layer and the second layer have a combined density substantially equal to or less than the density of water. A method of counteracting negative buoyancy in a personal protective device is also disclosed.
