The Callaway FT-iZ Tour driver features a 1-degree open face angle for more workability and an entirely new design to provide more distance and accuracy than ever before. It utilizes Polar Weighting which entails a heavy face and in-line power source in the back of the head, increasing stability, consistency, and linear acceleration of the ball. The Chemically Milled Hyperbolic Face Cup removes unwanted material from the face for precision thicknesses through a chemical reduction process. Its Fusion Technology design utilizes extreme weight placement through titanium, compression cured carbon fiber, cast steel, and formed aluminum.
