Claim:
A golf club head that, when oriented in a reference position, comprises: a striking face including a face center and a center apex; a bottom portion and a top portion opposite the bottom portion, the top portion including an exterior surface; a hosel including an imaginary centerline and an imaginary vertical hosel plane containing the imaginary centerline; a forwardmost point and a rearwardmost point opposite the forwardmost point; and an overall width, W o , wherein, in an imaginary vertical plane perpendicular to the imaginary vertical hosel plane and spaced from the face center by a lateral distance no greater than 0.25*W o : the exterior surface of the top portion includes a path comprising a first point and a second point rearward of the first point; an imaginary infinite straight line passes through the first point and the second point, but does not penetrate the exterior surface of the top portion, a segment of the imaginary straight line delimited by the first point and the second point; a two-dimensional space is bounded by the first point, the second point, the path, and the imaginary infinite straight line; a maximum distance, D max , measured perpendicular to the imaginary straight line, between the segment and the exterior surface of the top portion, is no greater than 0.70 mm; a distance D 1 between the first point and the second point is no less than 22 mm; and a distance D 2 between the first point and the center apex, as projected into the imaginary vertical plane, is no less than 40 mm.
