Multi-component golf club head
First Claim
1. A golf club head comprising a first body portion and a second body portion, the first body portion including a front face having a geometric face center;
- the club head having a center of gravity of at least about 5 mm lower than the geometric face center;
the first body portion composed of a first material having a density, the second body portion composed of a second material having a density that is less than the density of the first material; and
the second body portion forms at least a crown section, and a substantial portion of a skirt section.

Abstract
A metal wood golf club head adapted for attachment to a shaft, with a body comprising of a first body portion and a second body portion, each portion constructed of a different density material. Combining a high density material in the first body portion with a low density material in the second body portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. Thickening the lower area of the front face lowers the center of gravity and upwardly shifts the coefficient of restitution to the geometric center of the face
