1. A hollow golf club head comprising:
a strike face and a rear wall opposite the strikeface, each of the strike face and the rear wall having an inner surface, an outer surface, and a thickness between the inner surface and outer surface;
a sole and a top rail opposite the sole, each of the sole and the top rail having an inner surface, an outer surface, and a thickness between the inner surface and outer surface;
wherein the inner surfaces of each of the strikeface, rear wall, sole, and top rail cooperate to define a closed internal volume therebetween;
wherein the rear wall comprises an upper rear wall, a lower rear wall, and an exterior cavity;
wherein the upper rear wall directly abuts the top rail, and the lower rear wall directly abuts the sole; and
wherein the exterior cavity defines a concave, open external cavity located between the upper rear wall and the lower rear wall, the exterior cavity including:
a top cavity wall, a back cavity wall, and a bottom incline;
wherein:
a first end of the top cavity wall is connected to an end of the upper cavity wall to define a rear angle therebetween;
a second end of the top cavity wall is connected to a first end of the back cavity wall to define a back cavity angle therebetween;
the top cavity wall couples the back cavity wall with the upper rear wall;
a first end of the bottom incline connected to a second end of the back cavity wall, and a second end of the bottom incline connected to an end of the lower rear wall; and
wherein the closed internal volume extends between the inner surface of the top cavity wall and the inner surface of the top rail and between the inner surface of the strike face and the inner surface of the upper rear wall.
