The Delta Swim System is designed to aid in progressive swimming development, and is perfect for ambulatory individuals with postural balance and arm control. The front and back sections are designed to enhance the body's center of buoyancy, and the unique crotch strap design keeps the Delta in place. It is ideal for rehabilitation involving walking in deep water, running, and aerobic exercises. The Delta can also be used to pinpoint muscle strengthening during resistance training. This component system is made with removable pieces; as your swimming skills improve, pads can be removed to help you achieve independence. For additional buoyancy or equalization of balance, see pad plus (model 8721) Please note: Custom colors and/or modifications to any product require up to 7 days for fabrication. Custom and/or modified items are not returnable.
