Product Overview: Hundreds of face geometries were simulated in order to create a driver that could deliver higher ball speeds, maximum distance and incredible forgiveness. With a huge sweet spot that extends out towards the toe and heel, the D9 driver is always on, even when you’re a little off. Features: MAXIMUM DISTANCE OFF MORE OF THE FACE Every millimeter of the has been honed for performance. By dividing the face into a series of fractal zones, each tuned for explosive distance, our Peak Kinetic Response Face optimizes both forgiveness and ball speed. SOUND, FEEL AND PERFORMANCE The three-layer [K]COMPOSITE CROWN is made from Kevlar® and carbon fiber to neutralize vibration for a solid feel and satisfying acoustics.  It’s also incredibly lightweight, which means a lower center of gravity and faster club head speeds for better ball flight and more distance.
