1. A golf club head comprising:
a strike face having a top edge, a bottom edge, and a geometric center, the strike face defining a loft plane positioned tangent to the strike face extending through the geometric center; and
a body including:
a front end, a back end opposite the front end;
a heel, a toe opposite the heel;
a crown including an apex and a crown transition profile, the crown transition profile having a first crown radius of curvature extending from the top edge of the strike face to a first crown transition point, wherein the first crown radius of curvature is between 0.18 inch and 0.30 inch;
a sole including a lowest point and a sole transition profile, the sole transition profile having a first sole radius of curvature extending from the bottom edge of the strike face to a first sole transition point, wherein a ratio of the first crown radius of curvature to the first sole radius of curvature ranges from 0.4 to 1.0;
a rear transition profile positioned between a first rear transition point, and a second rear transition point, the rear transition profile having a rear radius of curvature between 0.10 inch and 0.25 inch; and
wherein the rear transition profile includes a height measured as a distance between the first rear transition point and the second rear transition point, wherein the height ranges from 0.10 inches to 0.26 inches.
