Inflatable life jacket

A life jacket comprising:

• a shell having an interior chamber constructed of an air-impervious material with a neck opening allowing a lower section of the shell to be placed on the front torso of a user and an upper section of the shell to be placed behind the user's head;
• a reusable seal attached to said upper section of said shell, configured to selectively open and close access to said interior chamber;
• a fastening assembly having a first element coupled to a first edge of said upper section and a reciprocal element coupled to a second edge of said upper section;
• an attachment strap coupled to said lower section of said shell and configured to wrap around the torso of the user to secure said shell to the user's torso;
• and
• a manually operable air valve in fluid communication with said interior chamber, wherein said air valve is configured to permit manual insertion of air into said interior chamber by a user and to selectively retain said air within the chamber to increase buoyancy of the life jacket;
• wherein said life jacket has a deflated condition in which said reusable seal is open, permitting said shell to be folded or rolled into a compact configuration for storage, and an inflated condition in which said reusable seal is closed to trap air within said interior chamber;
• and
• wherein, in said inflated condition, said upper section of said shell is rolled at least two turns and secured by engagement of said fastening assembly, thereby preventing unrolling of said upper section, and compressing trapped air within said interior chamber to maintain buoyancy.
