Golf club head

A golf club head comprising:

• a body having a bottom portion, a top portion, a front portion, a back portion, a heel portion, and a toe portion;
• a sole located on the bottom portion of the golf club head;
• a face positioned at the front portion of the body, the face being configured to receive an impact;
• a top portion silhouette profile located along a perimeter of the top portion, the top portion silhouette profile defining outer bounds of the top portion in an X-direction and Y-direction, the golf club head having a bottom portion volume below the top portion silhouette profile and a top portion volume above the top portion silhouette profile;
• a center sole portion extending from the front portion of the body to the back portion of the body, the center sole portion comprising:
• a lower surface extending rearwardly along the bottom portion of the golf club head in a generally Y-direction;
• a toeward sole surface that slopes upwardly from the lower surface when viewed in an address position;
• a first edge extending in a generally Y-direction on a toe side of the lower surface and defining a transition between the lower surface and the toeward sole surface;
• a heelward sole surface that slopes upwardly from the lower surface when viewed in the address position;
• and
• a second edge extending in a generally Y-direction on a heel side of the lower surface and defining a transition between the lower surface and the heelward sole surface;
• wherein the lower surface is a lowest portion of the golf club head that is both integrally formed with the golf club head and located rearward of the center of gravity;
• wherein the golf club head has a head origin defined as a position on a face plane at a geometric center of the face, the head origin including an x-axis tangential to the face and generally parallel to a ground plane when the head is in the address position where a positive x-axis extends towards the heel portion, a y-axis extending perpendicular to the x-axis and generally parallel to the ground plane when the head is in the address position where a positive y-axis extends from the face and through a rearward portion of the body, and a z-axis extending perpendicular to the ground plane, to the x-axis and to the y-axis when the head is in the address position where a positive z-axis extends from the head origin and generally upward;
• wherein the top portion silhouette profile comprises at least a first contour extending along an outer toe edge of the club head and a second contour extending along an outer heel edge of the club head, wherein the first contour extends at least from a toe-side forward portion to the back portion of the golf club head and the second contour extends at least from a heel-side forward portion to the back portion of the golf club head;
• wherein the first contour and the second contour are asymmetric about a Y-Z plane passing through a rearward most point of the golf club head and a majority of the first contour is curved and a majority of the second contour is curved;
• wherein the golf club head has a center of gravity with an x-axis coordinate, a y-axis coordinate between about 15 mm and about 50 mm, and a z-axis coordinate less than about 2 mm,
• wherein a front-rear dimension is at least about 111 mm and no more than 127 mm, a maximum club head height (H) is no more than 71 mm, and a heel-toe dimension is no less than the front-rear dimension;
• and
• wherein the bottom portion volume is greater than 60 percent of a total volume of the golf club head.
