The Srixon Z-URC golf ball is a 100+ compression 3-piece construction ball that is ideal for those golfers who generate a faster club head speed. It starts with a proprietary Polybutadiene formulation at its core; a high velocity resilient ionomer boundary layer and the softest urethane-elastomer cover Srixon have ever developed which delivers outstanding spin control on approach shots and around the green because of the high quality and great softness of this cover. At an astounding .02 inches thin, this unique cover provides for the largest and fastest Energetic Gradient Growth core Srixon has ever developed, meaning you don't have to sacrifice distance to gain this control. Finally, the 330 dimple pattern of the Srixon Z-URC combines low spin and a high trajectory with a penetrating ball flight for stability in all cross winds and head winds. All round, the Srixon Z-URC offers superior tour performance with optimum control and exceptional distance.
