The Volvik Green Crystal is a premium level 3-piece golf ball provides the ultimate in distance with a hyper soft feel. The Volvik Crystal 3-piece is the evolution of the original Crystal ball that revolutionized the color golf ball market. Explosive distance is provided by the combination of the innovative Power Core, Control Layer and Zirconium Z-I Outer Cover. Volvik’s high resilient dual core optimized with its more solid inner core provides high energy transfer of power from the inner core for maximum distance. This world leading technology is the world’s first patent and covers the USA, UK, Japan and Korea. The dual core optimizes distance by transferring the power from the more solid inner core to the softer outer layer instead of transferring inertia from a soft inner core to a solid outer layer like the competition. A distinctive putting feel and optimal spin rates are made possible by more durable/softer Surlyn crystalline cover and the patented 350-Octahedron dimple pattern. This may contain a mixture of different year models.
