Built Honestly for Slicers
Rather than a general-purpose driver with vague forgiveness claims, the B21 targeted a specific golfer profile head-on: those fighting a persistent slice. The low, forward CG dropped spin directly, addressing the root cause of a slice rather than just adding more perimeter weighting.
Flash Face SS21 and Jailbreak Together
Flash Face SS21 optimized the AI-designed face for the B21's specific mission, while Jailbreak Technology's internal bars added stability and further boosted ball speed, real, proven Callaway technology in service of a genuinely honest positioning.
