1. A golf club head comprising:
a head body comprising a head interior bounded by a head front portion, a head rear portion, a head heel portion, a head toe portion, a head top portion, and a head sole portion;
a strikeface at the head front portion comprising a strikeface height and a geometric centerpoint, the strikeface height being between 33 mm and 71 mm, and the geometric centerpoint positioned at a midpoint of the strikeface;
a head depth length measured from the geometric centerpoint of the strikeface to an intersection of an exterior of the head rear portion by a head depth plane;
a head center of gravity having a head CG depth and a head CG height;
wherein:
the golf club head comprises a driver-type body;
the head CG height is less than or equal to 2.54 mm;
the head CG depth is approximately 70 mm to approximately 102 mm;
a head volume of the golf club head is greater than approximately 450 cc;
a head weight of the golf club head is approximately 185 grams to approximately 225 grams;
more than 25% of a mass of the golf club head is located in a rearmost 20% of a length of the golf club head;
a fixed weight positioned on the head sole portion, wherein the fixed weight is located:
within 1 inch from a perimeter of the head rear portion; a distance from a front plane of the golf club head greater than 4.0 inches;
a distance from the head center of gravity greater than 1.5 inches;
a crown angle less than 70 degrees when measured in a side cross sectional view of the golf club head taken through the geometric centerpoint of the strikeface wherein the crown angle is measured between a front plane and a crown axis that extends through a transition point of the head top portion and a rear transition point of the golf club head; and
a maximum head top portion height greater than approximately 20 mm wherein the maximum head top portion height is measured as a greatest distance between the head top portion and the crown axis.
