Ping Si3 Driver. With its state-of-the-art fully forged face technology, the Si3 Driver Series advances driving performance for golfers of all abilities. By wrapping the face around and connecting it to the body of the driver, Ping engineers created a large, thin titanium face for maximum distance, forgiveness and strength. This Si3 340 (340cc) appeals to golfers seeking the performance and workability of a smaller head. With its proprietary lightweight shaft and grip, the total weight of each driver is approximately 300 grams. This makes it easier to swing, helping the golfer produce faster swing speeds - and longer drives.
