A buoyancy vest is a type of personal flotation device designed to help individuals stay afloat in water. It is typically made from lightweight materials that provide buoyancy, allowing users to float with minimal effort. These vests are commonly used in activities like boating, kayaking, and swimming to enhance safety. Buoyancy vests come in various styles and sizes, often featuring adjustable straps for a secure fit. Unlike traditional life jackets, they are less bulky and allow for greater freedom of movement, making them popular among water sports enthusiasts. Always ensure the vest is properly fitted for maximum effectiveness.
