A swim buoy is a floating device used by swimmers for safety and visibility while swimming in open water. It is typically brightly colored and can be towed behind the swimmer, making it easier for boats and other watercraft to see them. Swim buoys often have a storage compartment for personal items, such as keys or snacks, allowing swimmers to carry essentials while enjoying their swim. These buoys are popular among triathletes and recreational swimmers alike, as they provide an added layer of security during training or races. Many swim buoys are designed to be lightweight and easy to inflate, making them convenient for transport and use in various water conditions.
