Abstract

A golf club may include a front surface, a rear surface having a recess, and an insert at least partially disposed in the recess. The insert may comprise a durometer hardness of less than about 95 Shore A and a cavity having a reinforcement member disposed therein. Preferably, the durometer hardness of the reinforcement member is also less than about 95 Shore A. The insert may further comprise an anterior perimetric boundary having a first length and a posterior perimetric boundary having a second length. The ratio of the first length to the second length may be less than 1 and greater than 0.5. In one example, the insert may have a triangular front profile and a triangular side profile.

5. The golf club head of claim 4 , wherein the volume of the recess is between about 1 cm 3 and about 3 cm 3 .

6. The golf club head of claim 1 , wherein the insert comprises a triangular front profile.

7. The golf club head of claim 6 , wherein the insert comprises a triangular side profile.

8. The golf club head of claim 1 , wherein the rear surface comprises a muscle portion, the insert being disposed entirely within the muscle portion.

9. The golf club head of claim 1 , wherein the insert further comprises an anterior side and a posterior side, the cavity being disposed on the posterior side.
