Zone - Ultra Low RG Cores
Bowling's most popular brand name "Zone", features both Symmetric and Asymmetric versions of Ultra-Low RG Core Technology, combined with EnMotion Reactive Coverstock. Ultra–Low RG cores concentrate more mass at the center of the ball. This helps to create a strong revving action that improves the read of the mid-lane and delivers a continuous back-end hooking action.
