Product Description

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. They're engineered for players who want fast ball speed, high launch, straight shots and a new level of confidence.

  • Irons - 5-PW, SW
  • 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.
