From the outside-in, the new Srixon AD 333 is unlike any other two-piece ball on the market today. Outside - The AD 333 utilizes a brand new, revolutionary "Rabalon" blended elastomer cover which is exclusive to Srixon. This soft and durable material is 35% more resilient than standard ionomer materials. It provides greater ball speed and initial velocity off the tee while providing soft feel and spin on all shots from tee to green. The AD 333 also features a new, aerodynamically superior 333 dimple pattern that provides greater low-velocity lift for increased carry and roll. Inside - The AD 333 is powered by Srixon's proprietary super-soft E.G.G. core which is firmer on the outside and gets progressively softer towards the center. It delivers the optimal launch conditions - high launch angle with low-spin. Features: 2-Piece Construction Brand New "Rabalon" blended Elastomer Cover Aerodynamically superior 333 dimple pattern, the world's first to feature an odd number of dimples
