You’re looking for more distance, and the Big Bertha B21 Irons and Hybrids are here to give it to you. In fact, we’ve designed our legendary Big Bertha shaping with a NEW formula for distance and forgiveness...any way you swing it.
Fast Ball Speeds From The First A.I. Designed Big Bertha Irons
High ball speeds and increased spin robustness from our industry-leading A.I Flash Face Cup. Ball speed is further enhanced by our 360 Face Cup that flexes and releases at impact.
Improved Turf Interaction From Legendary Big Bertha Shaping
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, we've added more offset into the head.
Easy Launch From Our Visible Tungsten Energy Core
Now you can get higher launch conditions through the set. We've added a significant amount of custom tungsten weighted, so we can deepen the CG with extraordinary precision while still maintaining high ball speeds.
Pure Feel From Urethane Microspheres
Callaway's patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
Fast Ball Speeds From Flash Face SS21
Fast ball speeds across an expansive area in each model and loft, with our advanced A.I.-designed Flash Face. So you’ll hit it long, even if you miss the center of the face at impact.
Straighter, Longer Ball Flight From Increased Offset
We’ve added more offset to help reduce your slice or big miss. This increased offset helps to promote a straighter ball flight for more distance.
Enhanced Launch and Trajectory Control From Dual MIM’ed Tungsten Weighting
Optimized CG for launch and stability from precisely shaped dual MIM’ed tungsten weight.
Increased Ball Speed And Easy Launch
Two internal Jailbreak bars connect the sole and crown, so the face can take on more of the load at impact. For higher MOI in a forgiving shape, we've used a significantly lighter carbon crown so we can redistribute weight.
