Keep yourself in place during your aerobic water workout. Water Gear's swimmer's leash is designed to hold you in place while swimming or exercising. Belt length is 52" inches and is adjustable. Includes a 10 foot stretch cord. The nylon web belt is attached around the waist and the other end of the leash is attached to a fixed point on the edge of the pool, thereby allowing you to swim in place in small pools or limited space situations. The stretchable cord maintains tension while exercising.
