Golf club head

A golf club head comprising:

• a face component composed of a first material, the face component comprising a striking plate portion and a return portion, the striking plate portion having varying thickness, a substantially rectangular shape and an aspect ratio greater than 1.8;
• and
• an aft-body coupled to the return portion of the face component, the aft-body composed of a second material having a density less than that of the first material, the aft-body comprising a crown portion, a sole portion, the sole portion having a bottom section and a ribbon section, the ribbon section being located between the crown portion and the bottom section of the sole portion;
• wherein the golf club head a mass ranging from 180 grams to 215 grams, a volume ranging from 420 cubic centimeters to 470 cubic centimeters, a moment of inertia, Izz, about the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia, Iyy, about the center of gravity of the golf club head ranging from 2000 grams-centimeters squared to 4000 grams-centimeters squared;
• wherein the golf club head has a coefficient of restitution ranging from 0.825 to 0.883, and the golf club head has a standard deviation of coefficient of restitution of greater than zero and less than 0.226.
