Life Preserver

A life preserver, also referred to as a personal flotation device (PFD), life jacket or life vest is a sleeveless jacket that is designed to enable the wearer to float when they are in water. Life preservers automatically force the wearer into a position whereby they are facing upwards - this keeps the nose and mouth out of the water, helping to lower the risk of drowning - something that is especially important if the wearer is unconscious when they fall into the water.
