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 cavity therebetween;
the rear wall comprises an upper rear wall, a lower rear wall, and a bottom incline extending between the upper rear wall and the lower rear wall;
the upper rear wall extends from and is directly coupled to the top rail, and the lower rear wall extends from and is directly coupled to the sole;
the bottom incline has a first end that is connected to the upper rear wall to form an inflection angle of between 95 degrees and 150 degrees, the inflection angle measured between an outer surface of the upper rear wall and an outer surface of the bottom incline;
the bottom incline has a second end that is opposite the first end and is connected to the lower rear wall to form a lower angle of between 130 degrees and 175 degrees, the lower angle measured between an outer surface of the bottom incline and an outer surface of the lower rear wall; and
wherein the thickness of the strikeface, measured between the inner surface and the outer surface of the strikeface, is in the range of 0.04 inch (1.016 mm) to 0.10 inch (2.54 mm), and the thickness of the top rail, measured between the inner surface and the outer surface of the top rail, is in the range of 0.04 inch (1.016 mm) to 0.08 inch (2.032 mm).
