Abstract
A personal flotation device in the form of a vest having two chest portions that are interconnected by a neck portion. The vest fits over a user's head and is secured to the user by way of a belt and a chest strap. The vest is inflatable by the user and in a deflated condition, the chest portions are folded upon themselves to present a low profile vest that may be worn by the user without interfering in marine activities. A plurality of frangible fasteners are disposed on flap portions of the chest portions to retain the chest portions in their folded condition, yet release the flap portions under inflation pressure.
