A golf club head includes: a sole; a crown; a toe; a heel opposite the toe; a strike face generally bounded by a face perimeter edge, the strike face comprising a geometric center; a rear portion; and a substantially enclosed interior cavity at least partially delimited by the sole, the crown, the strike face, and the rear portion. The golf club head also includes at least one rib having a first portion secured to the strike face, having a second portion secured to the crown, and being positioned such that a location on the strike face laterally spaced toe-ward from the geometric center by no less than 0.4 in is associated with a COR value no less than 0.825.

Golf club head

A golf club head includes a main body having a top portion, a bottom portion, a striking face, and an interior surface. A weight member is coupled to the interior surface of the main body. In an imaginary vertical plane that passes through the weight member, the interior surface of the main body comprises a first point and a second point. An imaginary line passes through the first point and the second point. A first imaginary boundary line and a second imaginary boundary line, both passing through the weight member and being perpendicular to the imaginary line, pass through the first point and the second point, respectively. Between the first point and the second point, the interior surface of the main body has an irregularity factor of at least 1.2 and the weight member comprises a distribution factor of at most 1.0 and a conformity factor of at most 0.07.

Golf club head with a body-conforming weight member

An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.
