Callaway Big Bertha B21 Irons

Distance Any Way You Swing It

Fast Ball Speeds From The First A.I.-Designed Big Bertha Iron

For the first time, A.I.-designed Flash Face Cup is engineered into a Big Bertha Iron. This creates high ball speeds and increased spin robustness off every club in the set, with a unique Flash Face architecture for each individual iron. Ball speed is further enhanced with a 360 Face Cup that flexes and releases at impact.

Amazing Forgiveness From Legendary Big Bertha Shaping

The popular Big Bertha club profile is engineered to give you more confidence over the ball with noticeably wider soles. More offset is added for easy launch, lower spin and straighter shots. Combined with the Flash Face Cup, this is the new formula for distance and forgiveness.

Higher Launch From Visible Tungsten Energy Core

A significant amount of custom tungsten weighting has been added. This allows for the CG in each iron to be lowered with extraordinary precision, while still maintaining ball speed in the Flash Face Cup resulting in higher launch conditions through the set.

Pure Feel From Urethane Microspheres

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

Premium Components

Offered with a new RCH graphite shaft, designed by Callaway to specifically enhance the Big Bertha offering, or KBS Max CT80 steel.
