the first rear wall curve comprises a portion of a second circle having a second radius; and
the first circle and the second circle are approximately concentric.
9. A golf club head comprising:
a strike portion comprising:
a strikeface; and
a backface opposite the strikeface, the backface comprising a perimeter portion at a top end of the backface;
a rear portion coupled to the strike portion at a bottom end of the strike portion; and
a port structure at least partially defined within the rear portion, the port structure comprising a slot extending from a slot opening to a slot base; and
an insert located within and substantially conformal with the port structure;
wherein:
the slot further comprises:
a heel wall;
a toe wall;
a rear wall extending from the slot opening to the slot base, and extending between the heel wall and the toe wall, the rear wall comprises a first rear wall curve along a first direction extending between the slot opening and the slot base wherein the first rear wall curve is convex in the first direction extending between the slot opening and the slot base; and
a front wall extending from the slot opening to the slot base, and extending between the heel wall and the toe wall, the front wall comprises a first front wall curve along the first direction, the strikeface being located closer to the front wall than the rear wall; and
the strikeface further comprises:
an upper region located above the slot opening of the port structure, the upper region comprising a minimum upper thickness measured from the strikeface to the backface in a direction perpendicular to the strikeface;
a lower region located below the slot opening of the port structure, the lower region comprising a minimum lower thickness measured from the strikeface to the front wall of the slot in a direction perpendicular to the strikeface; and
the minimum lower thickness of the strikeface is less than the minimum upper thickness of the strikeface.
