Volvik Vivid XT White Golf Balls - Extreme Distance, Premium Performance, Game-Changing Look. The VIVID XT is a brand new premium golf ball from Volvik and one of the most unique balls on the market. In fact, it's the only four-piece golf ball available to the public that doesn't have a urethane cover, as the XT's cover is made of Zirconium. Also unique is that the VIVID XT features a matte finish that was specifically designed for the World Long Drive circuit. That combination produces a ball that's extremely durable and aerodynamic, but it still offers exceptional greenside spin and control. But where the XT excels is from a distance standpoint, as it produces extremely low spin rates off the driver. It's also a ball that's recommended for higher swing speed players, ideally those who are above 100 MPH with a driver, according to Volvik. Volvik Vivid XT White Golf Balls features: * Compression: 100 * Matte finish reduces air resistance * Dual Power Core creates faster ball speeds for more distance * Developed for players with swing speeds of 100 MPH and higher * Four-piece construction delivers optimal performance from tee to green * Low spin rates off a driver produce enhanced distance * Designed for mid-to-high trajectory on full shots and maximum spin around the greens.
