The Z-UR features all the power of Srixon technology harnessed into our longest, most playable tour performance ball yet. It features an incredible membrane-thin urethane elastomer cover, which surrounds the largest, fastest energetic gradient growth core we’ve ever developed. A proprietary compound called bis (pentabromophenyl) disulfide or PBDS added to the core delivers amazing resilience and initial ball velocity with low spin. The 330 dimple pattern combines high trajectory with a penetrating ball flight for stability in all cross winds and head winds. The soft and shear-resistant polyurethane cover means the Z-UR lands gently, and stops where it lands. This will include the ZUR & the ZUR-S.
