1. A golf club head comprising:
- a total mass between about 150 g and about 250 g;
at least one non-metallic portion comprising at least about 8% of the total mass;
a break length, between about 96 mm and about 140 mm, measured at a vertical distance between about 5 mm and about 10 mm from a ground plane; and
a volume of at least about 300 cm3.

Abstract
An exemplary golf club head having additional discretionary mass may be realized by utilizing light-weight materials, an favorable average crown height, and/or articulation points. By using a preferred break length, the additional discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.
