Defender Hybrid was the first Brunswick ball featuring the groundbreaking new coverstock base, HK22. The motion was more hook in oil and more backend for a shiny ball than had ever been seen in the Brunswick line. HK22 balls have evolved significantly over the last year and a half. We’re excited to continue the evolution of the innovative cover base with the Ultimate Defender. This ball produces exceptional hook in the oil and impressive continuation on the backend because of the clean and strong nature of the cover despite the dull surface. The Ultimate Defender will be your ultimate choice when combating oily conditions. Compared to the Mindset, the Ultimate Defender will be cleaner and sharper while still handling the oil conditions.
