The best players on the beach are always one step ahead. When you can read and react to where the game is going, you can be too. The breakthrough design of the OPTX AVP Tour Replica Volleyball brings a whole new visual approach to the beach. New VST™ (visual spin technology) uses strategic color variance to enhance the human eye's ability to detect spin on the ball. A vibrant color palette and Optic Flow graphics allow the ball to be more easily tracked in the diverse environments of beach volleyball, like clouds, sky, sand, water, and crowds.
