The Mikasa MVA200 Indoor Volleyball is tested and ready for high-quality performance in the Olympic Arena and was used in the 2008 Olympic Games in Beijing, China. Features include an eight-panel swirl design that allows for more contact area on the surface to improve passing and control and a unique dimpled microfiber material that creates turbulence and cuts down on resistance as the ball flies through the air. This lack of resistance allows the ball to fly through the air in a truer form so you can be creative with your serves and spikes.
