Callaway Big Bertha B21 Irons

The First Big Bertha Iron Designed With A.I. You’re looking for more distance, and the Big Bertha B21 Irons 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.

Features & Benefits

  • 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
    Our patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
