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.
