The StrechCordz Safety Long Belt Slider is used for adding resistance to swimming and is StrechCordz's #1 in-water resistance product.
It provides swim out and pull-back resistance to improve strength and stamina. Accelerate quicker, strengthen the finishes of each stroke and improve your times.
A proprietary, embedded safety cord runs the full length of the tubing and acts as a limiter to help prevent over-stretching.

The Safety Long Belt Slider features a 2-in/5 cm waist belt that fits up to a 44-in/1.1 m waist, padded for comfort and connected to 20 feet/6 m of latex with safety cord tubing and sliding attachment that moves freely around the belt for unrestricted movement.

Used in either 25yd or 25m pools. Interchangeable.
