Superior performance is achieved with a combination of Gamma's patent pending Thinex™ Technology core, nitrogen gas infusion and custom manufactured TexTech felt. Gamma Pro Tour makes the first significant evolutionary step in ball performance since 1922 when balls first became pressurized and the ball core became thinner to improve playability. The result is a higher level of performance than any other tournament ball.
