The term "life vests" is commonly used to describe a type of personal flotation device worn to stay afloat in water. However, there are several synonyms for this term such as life jacket, personal flotation device, buoyancy aid, and life preserver. These synonyms can be used interchangeably, but some may have specific meanings in certain contexts. For example, a life jacket typically refers to a buoyancy aid worn on boats, while a personal flotation device may be used for water sports. Regardless of the term used, wearing a life vest or any other type of buoyancy aid can help to prevent drowning and increase safety while in or near water.
