1. A golf club head comprising:

  • a wood type golf club head body including a ball striking face portion at a front side thereof, a rear side opposite the front side, a crown portion, and a sole portion;

    the golf club head body comprising an imaginary XY coordinate axis,wherein a Y-axis is defined in a front-to-rear direction perpendicular to a front tangent and a rear tangent through a geometric center of the golf club head, andwherein an X-axis is defined in a heel-to-toe direction perpendicular to the Y-axis through the geometric center of the golf club head,the golf club head body including;

    a maximum breadth that extends from a forwardmost point of the ball striking face portion to a rearwardmost point of the rear side;

    a maximum depth that extends from a topmost point of the crown portion to a bottommost point of the sole portion;

    a first portion of the golf club head body that extends from the crown portion to the sole portion and includes a first depth of the golf club head body;

    a second portion of the golf club head body that extends from the crown portion to the sole portion and includes a second depth that is less than the first depth;

    wherein the sole portion of the golf club head body is configured so that it includes;

    a sloped boundary portion that separates a sole region of the first portion from a sole region of the second portion, wherein the sloped boundary portion has a height of at least 2 mm and extends from the sole region of the first portion to the sole region of the second portion, thereby defining a transition in depth between the first portion and the second portion of the golf club head body;

    further wherein the sloped boundary portion extends so as to define a rear heel quadrant of the golf club head body,wherein the rear heel quadrant of the body is heelward of the Y-axis and rearward of the X-axis; and

    wherein the first portion of the golf club head body is the rear quadrant of the golf club head body,further wherein the first portion and second portion are configured so that a center of gravity of the golf club head body is positioned nearer to the rear heel quadrant than the toe edge or the front side,wherein at least 26% of the mass of the golf club head body is in the first portion of the golf club head body.
