## Description

The Defender borrows from recent successful Brunswick releases to ensure confidence and performance. Starting with the core, our engineers took the Prism core shape and added a dense flip block to the bottom. This core configuration moves mass away from the center of the core body, creating a higher RG and more total differential, enhancing down-lane motion. The updated ACT 3.0 Solid cover was designed to strengthen the mid-lane and backend hook. The attractive color combination, Portal X core, ACT cover, and 2000 Siaair finish are the perfect recipe for higher scores.
