The Ping Si3 is a round 380cc head with a deep face providing confidence at address. The internal weighting design positions weight in the center of the face of the Ping Si3 to promote long, straight tee shots. The very thin forged titanium face is engineered for strength to offer forgiveness and control on the Si3 380 driver.
