A golf club head comprises a club head body having an external surface with a heel portion, a toe portion, a crown, a sole, and a face. The golf club head has a moment of inertia about a CG Z axis, IZZ. In some implementations, IZZ is greater than 4150 g·cm2 or greater than 4400 g·cm2. The face comprises a bulge curvature that satisfies a predetermined mathematical relationship. In some implementations, a moment of inertia about the CG X axis, Ixx, exceeds a predetermined value, and Izz is greater than Ixx. The face can comprise a roll curvature, and a ratio of the bulge curvature divided by the roll curvature, RC, can be greater than 0.28 and less than 0.75. |
