Advanced technology never felt so good. This amazing driver delivers the performance of a sophisticated steel design, yet maintains the sound and sensation of persimmon for an unbelievably pure feel. The Blue Steel Driver features a high-density face for maximum coefficient of restitution (COR) and greater distance. In addition, the driver’s center of gravity is positioned low to provide more forgiveness in getting the ball airborne, and it’s received the highest player testing ratings for playability. Once you hit and hear the Blue Steel Driver, you'll fall in love with its pure sound and feel.
