Callaway Big Bertha B21 Combo Iron Set 7 Pc Graphite Shafts
Fast Ball Speeds From Flash Face SS21
Fast ball speeds across an expansive area in each model and loft, with Callaway's 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
Callaway has 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, Callaway has used a significantly lighter carbon crown so we can redistribute weight.
Fast Ball Speeds From The First A.I. Designed Big Bertha Irons
High ball speeds and increased spin robustness from Callaway's 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, Callaway has added more offset into the head.
Easy Launch From Our Visible Tungsten Energy Core
Now you can get higher launch conditions through the set. Callaway has added a significant amount of custom tungsten weighted, so they 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.
