A personal flotation device (also named PFD, lifejacket, life preserver, Mae West, life vest, life saver, cork jacket, life belt) is a device designed to keep a wearer afloat and their head above water, often in swimming pools, rivers, lakes, and oceans. The term includes all types of such devices from life preservers to lifejackets to survival suits. They are available in different sizes and different designs purposed for various levels of protection.
Lifejackets or life vests are the most multiform of personal flotation devices. They are mandatory on airplanes travelling over water and are also found on sea-faring vessels, accessible to all crew and passengers and to be donned in an emergency. Floatation devices are also found in near water-edges and at swimming pools. They may appear in the form of a simple vest, a jacket, a full-body suit, or their variations suited for particular purposes. They are often made of tough synthetic fiber material encapsulating a source of buoyancy, such as foam or a chamber of air, and are often brightly colored as yellow or orange to maximize visibility for rescues.
Foam core
The simplest and least buoyant of the class come in the form of nylon-lined foam vests, often used in training for swimming, or as light safety precautions in relatively safe environments, such as lake cruises and amusement parks. With no need for a leakproofing quality check because of their inherently buoyant foam cores, they can be mass-produced inexpensively and widely used, making it the most commonly seen form of lifejackets.
Life jackets for large commercial transport in potentially dangerous waters, such as coastal cruises and airlines, are often a sealed suit of heavy vinyl with an inflatable air chamber, and usually provides more buoyancy than its foam counterpart. The air chambers, usually located over the breast and back regions of the body, may be inflated by either self-contained carbon dioxide cartridges activated by the pulling of a cord, or blow tubes with a one-way valve for inflation by exhalation.
Drifting in open seas and international waters, as encountered by long sea voyages and military forces, require prolonged survival in water. The life jackets suited for this purpose are often also equipped with survival kits, usually containing signalling devices, first-aid kits, food, water, and shark repellent.
PFDs including 'wet' or 'dry'-suits are made that are intended for long term immersion in cold water. A flotation device known as the Steinke hood is used as an escape device to ascend from a stranded submarine.
The Mark 10 Submarine Escape and Immersion Equipment (SEIE) suit is intended to allow submariners to escape from much deeper depths than currently possible with the Steinke Hood. Some United States Navy submarines already have the system, with an ambitious installation and training schedule in place for the remainder of the fleet.
Because it is a full body suit, the Mark 10 provides thermal protection once the wearer reaches the surface, and the British Royal Navy has successfully tested it at six hundred foot depths.
Origins
Ancient instances of the lifejacket can be traced back to simple blocks of wood or cork used by Norwegian seamen. The modern lifejacket is generally credited to one Captain Ward, a Royal National Lifeboat Institution inspector in the United Kingdom, who, in 1854, created a cork vest to be worn by lifeboat crews for both weather protection and buoyancy.

Mae West
The Mae West was a common nickname of a Type B-4 life preserver (inflatable lifejacket), used during World War II by the Allies. The B-4 was invented by James F. Boyle. The preserver was khaki color, made of cotton with inflatable rubber bladders, with dimensions of 27.5" H x 12.75" W x 1.25" D. The nickname was based on the famously buxom figure of Mae West, one of the most popular actresses of that period.
Andrew Toti related that his mother was the inspiration for the invention of the Mae West life vest. He had bought a boat, and his mother was worried because he couldn't swim. He designed a personal life preserver filled with duck feathers. However, that was too bulky and heavy, so he used air. Toti sold the rights of the Mae West life vest to the US War Department in 1936 for £800
