Abstract: Luggage, such as suitcases and backpacks, converts into personal flotation devices by incorporating flotation elements into their structure. Backpacks can also be converted to rescue harnesses by the incorporation of a reinforcing strap and rescue ring. Significantly, such multi-purpose items of luggage offer users access to safety devices unavailable to users of ordinary luggage, enabling such users to have access to lifesaving equipment without requiring the user to carry a dedicated PFD or rescue harness. In one embodiment a backpack includes an emergency lower opening that can be used to remove heavy items while the user is still wearing the backpack, to increase the buoyancy of the survival backpack by eliminating ballast. In another embodiment, a backpack includes a peripheral zipper that separates the backpack into first and second portions, one portion to be worn over the chest and the other portion to be worn over the back.
