A personal flotation device is abbreviated as P.F.D.

It is also referred to as a life jacket, life preserver, Mae West, life vest, life saver, cork jacket, life belt and a flotation suit!

It is a device designed to assist a wearer to keep afloat with his or her mouth and nose (airway) of his or her head’s face above the water surface when in or on water.

The inflatable life jacket is named after a famous actress, screen writer, play writer and a sex symbol Mae west.

The reason?

Must be because the inflated life jacket rose into two lovely curves in the front-reminded people of the voluptuous and attractive Mae West!.
