Abstract

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. A golf club head includes a means for defining an interior cavity including a first material having a first density. The golf club head also includes a first means for increasing a moment of inertia of the means for defining the interior cavity, a second means for increasing a moment of inertia of the means for defining the interior cavity, and a third means for increasing a moment of inertia of the means for defining the interior cavity. The first, second, and third means include a second material having a second density greater than the first density.
