Callaway Big Bertha B21 Iron Set
Big Bertha B-21 is the first Big Bertha Iron with our AI-designed Flash face mug. This Flash Face cup is an industry leader in every club. We have created high ball speeds and greater turning robustness with a sophisticated facial architecture that is unique to each loft. This club profile is designed to give you more confidence on the ball with noticeably wider soles. For an easy launch, bottom spin, and straighter shots, we’ve added more offset. We have added a significant amount of custom tungsten weight. So that we can deepen the CG on each plate with extraordinary precision, while maintaining the speed of the ball in the Flash Face Cup. Our proprietary urethane microspheres comprehensively absorb unwanted vibrations for an exceptional feel, while also maintaining fast ball speeds.
