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.

Brunswick’s most advanced technology. The strongest core and cover combinations we offer.

Versatile ball motion that is useful across various lane conditions, usually a continuous and strong arcing ball. Balls with higher numbers will have stronger overall reactions.

The higher the number the stronger the reaction shape – with 1 being the least and 100 the most.

    The Brunswick Defender Is A New Release From Brunswick A High End Ball That Really Gets The Through The Oil... Definitely First Ball Out Of My Bag For League Or A Tournament...
