Callaway Big Bertha B21 Iron Set 4-PW Steel Shafts
- 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.
- 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.
- 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.
- Callaway's patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
