A swimming jacket, also known as a swim vest, is a buoyant flotation device designed to provide support and keep swimmers afloat in the water. Made from materials like foam or inflatable sections, it helps beginners, children, and adults build confidence while swimming or participating in water sports. Swimming jackets ensure safety, allowing for free movement in the water while providing extra buoyancy. Ideal for swim training, recreational use, or open-water activities, they come in various sizes with adjustable straps for a secure and comfortable fit.
