A golf club head having a cavity back design with a recess therein for placement of a lightweight polymer material. The club head having a back surface of a club face. The polymer material only bonded to the recess by its perimeter with a predetermined void between the polymer and the back surface of the club face. The lightweight material allows for a larger club head and consequently a bigger sweet spot without increasing the overall weight of the club head. Unwanted vibrations caused upon the club head hitting a golf ball are dampened by a spring/mass system. The polymer material serves as the spring and a decorative medallion, which is attached only to the polymer and not the club head, provides the mass. Vibrations created by contact between club head and golf ball are dampened in accordance to material characteristics of the selected polymer.
