Swimmers are often provided with an inflated rubber jacket, also known as a buoyancy aid, to enhance their safety and support while in the water. These jackets help keep swimmers afloat, reducing the risk of drowning, especially for beginners or those who may struggle with swimming. Additionally, they can assist in maintaining proper body position and technique during training or recreational activities, allowing swimmers to focus on improving their skills without the constant effort of staying above water.
