The S120 cranks up the intensity of competitive swims with two-person tug-of-wars, barge pulls, and more! Make a splash in the pool with improved strength, form, and IM times. This stretchy set-up features two 44-inch waist belts connected by 8ft of heavy latex tubing.

Not interchangeable, no removable parts, one perfect resistance level. Resistance when stretched 1-3 times original length = 20-45lbs of pull.
