1. A golf club head comprising:
a body having an outer surface and an inner surface,
wherein the inner surface is not visible from an exterior of the golf head, the body comprising:
a strike face;
a sole;
a crown;
a skirt between the crown and the sole;
a heel;
a toe; and
a toe side transition region extending rearward from the strikeface to the skirt, the toe side transition region comprising:
a first tier directly abutting the strike face;
a first tier transition region directly abutting the first tier opposite the strike face;
a second tier directly abutting the first tier transition region rearward of the first tier;
a second tier transition region directly abutting the second tier opposite the first tier transition region; and
the inner surface extends across each of the first tier, the first tier transition region, and the second tier;
wherein;
the first tier comprises a first thickness that is substantially constant or decreases from the strikeface to the first tier transition region;
the second tier comprises a second thickness that is substantially constant or decreases from the first tier transition region to the second tier transition region, wherein the second thickness is smaller than the first thickness;
wherein;
each of the first thickness and second thickness is measured between the inner surface and outer surface of the body;
the outer surface is continuous across the transition region between the strikeface and the sole;
first and second tier lengths are measured in a direction from the strikeface towards a rear of the golf club head;
the inner surface of the first tier transition region comprises a first arcuate surface extending rearward from the first tier and a second arcuate surface extending forward from the second tier, the first arcuate surface being convex and the second arcuate surface being concave when viewed normal to the inner surface;
and the inner surface being continuous from the first tier to the second tier;
wherein;
the first arcuate surface comprises a first radius of curvature and the second arcuate surface comprises a second radius of curvature;
the first and the second radius of curvature of the first tier transition region are at least 2 times a difference between the first thickness and the second thickness of the first tier and the second tier, respectively.
