1. A golf club head comprising:
a body defining a hollow interior region, the body comprising a sole portion, a crown portion, a skirt portion, and a front portion comprising a strike face;
wherein the strike face comprises a face insert having a variable face thickness profile,
wherein the face insert:
is formed from multiple plies of composite material,
has a minimum thickness of less than 4.5 mm and a maximum thickness greater than the minimum thickness and less than 6.0 mm, and
has a maximum outer surface area of between 3,300 mm2 and 4,400 mm2; and
wherein:
the strike face comprises a central region defined by a 40 millimeter (mm) by 20 mm rectangular area centered on a geometric center of the strike face, wherein the central region is elongated in a heel-to-toe direction;
the strike face comprises a first coefficient of restitution (COR) weighting factor and a first COR value positioned on the strike face at the geometric center of the strike face corresponding to an (x, y) coordinate of (0, 0);
the strike face comprises a second COR weighting factor and a second COR value positioned on the strike face 10 mm above the geometric center of the strike face corresponding to an (x, y) coordinate of (0, 10);
the strike face comprises a third COR weighting factor and a third COR value positioned on the strike face 10 mm below the geometric center of the strike face corresponding to an (x, y) coordinate of (0, −10);
the strike face comprises a fourth COR weighting factor and a fourth COR value positioned on the strike face 20 mm toe-ward of the geometric center of the strike face corresponding to an (x, y) coordinate of (−20, 0);
the strike face comprises a fifth COR weighting factor and a fifth COR value positioned on the strike face 20 mm heel-ward of the geometric center of the strike face corresponding to an (x, y) coordinate of (20, 0);
the first COR weighting factor is 0.3267, the second COR weighting factor is 0.2256, the third COR weighting factor is 0.1395, the fourth COR weighting factor is 0.2263, and the fifth COR weighting factor is 0.0819;
a summation of the first, second, third, fourth, and fifth COR weighting factors is 1;
the first COR value is no less than 0.817, the second COR value is no less than 0.801, the third COR value is no less than 0.775, the fourth COR value is no less than 0.785, and the fifth COR value is no less than 0.720;
a weighted COR value is no less than 0.792, the weighted COR value comprising a summation of:
the first COR weighting factor multiplied by the first COR value,
the second COR weighting factor multiplied by the second COR value,
the third COR weighting factor multiplied by the third COR value,
the fourth COR weighting factor multiplied by the fourth COR value, and
the fifth COR weighting factor multiplied by the fifth COR value; and
within the central region, the minimum thickness of the face insert is more than 3.5 mm.
