1. A golf club head comprising:
a hollow body formed between a sole and a crown;
a front end comprising a strikeface extending between the sole and the crown and being operative to impact a golf ball;
a rear end;
a heel region;
a toe region opposite the heel region; and
wherein a ground reference plane is defined such that the ground reference plane is tangential to and in contact with at least a portion of the sole, and a front reference plane is defined such that the front reference plane is perpendicular to the ground reference plane and both tangential to and in contact with a forward most point of the strikeface; and
wherein a loft plane is defined such that the loft plane is tangential to and in contact with a geometric center of the strikeface;
wherein the sole and strikeface comprise the same material;
wherein the sole defines a cavity on an outer surface of the sole and behind the strikeface, the cavity comprising:
a front edge coincident with an outer profile of the sole;
a front surface extending inward from the front edge;
a rear edge coincident with the outer profile of the sole;
a rear surface extending inward and forward from the rear edge;
a cavity length measured in a toe to heel direction;
wherein the cavity further comprises a main portion and an inset portion;
wherein the main portion extends inward from the outer profile of the sole between the front edge and the rear edge;
wherein the inset portion extends from the main portion toward the strikeface;
wherein a plurality of axes are defined extending parallel to the loft plane and through the front edge at each of a plurality of locations along the cavity length;
wherein the inset portion is separated from the main portion by a first plane defined by the plurality of axes;
wherein a reference line is perpendicular to the loft plane and extends through the front edge; and
wherein within a cross-sectional plane defined by the reference line, a depth of the cavity, measured parallel to the loft plane and from the rear surface to the reference line, is the greatest at an apex;
wherein an apex axis defines a maximum depth of the cavity at any location along the length of the cavity;
the front surface further comprises a side wall extending into the cavity from the front edge, and an inner wall extending into the cavity from the rear surface that extends forward from the rear edge;
the inset portion is positioned at a first angle to the side wall and a second angle to the inner wall;
the first angle ranges from 85 to 95 degrees;
the second angle ranges from 85 to 95 degrees;
wherein the cavity comprises the same material as the sole such that the strikeface, sole, and cavity comprise the same material.
