A life jacket is a piece of safety equipment worn to help keep a person afloat in water. It is typically made from buoyant materials like foam, which provide floatation, and is designed to keep the wearer's head above water even if they are unconscious. Life jackets are commonly worn by people during water activities such as boating, kayaking, or swimming in rough waters. They are adjustable to fit snugly and are equipped with straps or buckles to ensure they stay on in emergencies.
