Defender. It has a Super Hero look, and you’ll feel like one when throwing it. 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.
