Designed With A.I.
High ball speeds and increased spin robustness from Callaway's industry-leading A.I Flash Face Cup. Ball speed is further enhanced by 360 Face Cup that flexes and releases at impact.
Improved Turf Interaction
A club profile that's engineered to give you more confidence over the ball with noticeably wider soles. For easy launch, lower spin and straighter flight, Callaway added more offset into the head.
Tungsten Energy Core
Now you can get higher launch conditions through the set. Callaway Big Bertha B21 Irons have added a significant amount of custom tungsten weights, to deepen the CG with extraordinary precision while still maintaining high ball speeds.
Pure Feel From Urethane Microspheres
Patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
