This reduces accident risk and supports a safer swimming experience. Robust and durable: The rope is made of two materials, durable nylon and steel wire. The buoys are made from high quality polyethylene plastic, lightweight, buoyant and stable. They resist tearing and fading from sun and water and are designed for long life.
