Simply put, Callaway Golf engineers have re-invented tour golf ball performance. This isnt a small step forward. Its a giant leap forward. The new Tour i Golf Ball is the most technologically advanced tour ball youve ever played, providing the perfect balance of breakthrough distance and control. Innovative 4-piece inertia technology utilizes a tungsten-infused outer core to shift weight away from the center of the ball, reducing driver spin for maximum distance and straighter shots.
