To get to the top, you need a ball that works just as hard as you do. The textured housing provides a clean and clear finish, while molded grooves reduce drag, allowing you to complete your next blow with the best. Product information: Nike Aerowsculpt technology uses moulded grooves to interrupt airflow across the ball for less drag and a more stable flight. The textured housing ensures a smooth feel for the ball when passing, shooting and dribbling. The rubber bladder helps maintain air pressure and shape.
