Buoyancy aids are safety devices designed to help individuals stay afloat in water. They are commonly used in activities like boating, kayaking, and swimming. Unlike life jackets, buoyancy aids provide some flotation but are not intended to turn an unconscious person face-up. They are typically made from foam or inflatable materials and come in various styles and sizes. These aids are essential for both beginners and experienced water users, as they enhance safety while allowing for greater freedom of movement. It is important to choose the right buoyancy aid based on the activity and the user's weight, ensuring proper fit and effectiveness.
