Abstract: An inflatable life preserver uses a novel packing method with a lightweight inflatable film that allows it to integrate with equipment so that it is not noticeable to the user in the uninflated condition and does not impede the user's operations. In the uninflated state, the bladder is folded and rolled in a way that minimizes the device footprint. The device can be attached to a MOLLE vest or other garment. In the inflated condition, the inflatable bladder material is unsupported and is constrained to provide buoyancy distribution to turn a user face-up at the water line.
