a volume of the golf club head is greater than 425 cc;

a crown transition region, positioned between the strikeface and the crown, including a crown heel to toe radius of curvature extending along an entire top edge of the strikeface from near the heel to the toe of the golf club head;

wherein the crown heel to toe radius of curvature is in a range of 3.0 to 3.5 inches;

a sole transition region, positioned between the strikeface and the sole, the sole transition region including a sole heel to toe radius curvature extending along an entire bottom edge of the strikeface from near the heel to the toe of the golf club head;

wherein an entirety of the sole heel to toe radius is in a range of 6.25 to 7.75 inches;

further comprising a plurality of turbulators positioned upon the crown; and

the crown comprises one or more thin regions each having a thickness, measured from an outer surface of the crown to an inner surface of the crown, of 0.017 to 0.020 inch, wherein the thickness of each thin region decreases in a direction from the strikeface towards the back end.

2 . The golf club head of claim 1 , further comprising:

a front radius of curvature between 0.18 to 0.30 inch, wherein the front radius of curvature extends from a top edge of the strikeface to a crown transition point, the crown transition point indicating a change in curvature from the front radius of curvature to a different curvature of the crown; and

a rear radius of curvature between 0.12 inch and 0.25 inch that extends between the crown and the skirt of the golf club head along a rear transition boundary from a first rear transition point located at a junction between the crown and the rear transition boundary and a second rear transition point located at the junction between the rear transition boundary and the skirt of the golf club head.

3 . The golf club head of claim 1 , wherein the plurality of turbulators project from an outer surface of the crown adjacent to a crown transition point between the strikeface and a crown apex;

wherein each adjacent pair of turbulators is separate and spaced apart to define a space between the adjacent pair of turbulators, and wherein each turbulator extends between the heel and the toe to define a turbulator width and extends between the strikeface and the back end to define a turbulator length;

wherein the turbulator length is substantially greater than the turbulator width;

wherein at least a portion of at least one turbulator is located between the strikeface and the crown apex; and

wherein a spacing between adjacent turbulators is greater than a turbulator width of each of the adjacent turbulators.
