Today marks the final release as far as the new Big Bertha B-21 product range goes. Thus far we’ve seen and heard about the metalwood family that comes packed with game-improvement qualities. Not to be outdone, the Callaway Golf Big Bertha B-21 delivers game-improvement characteristics in spades.

How do the Big Bertha B-21 irons deliver all of this game-improvement capability? They offer Flash Face Technology, a first for the Big Bertha name. If you hit the MAVRIK irons this year, you’ll know that they were hot and also featured Flash Face. They feature a deep centre of gravity to help golfers launch the ball into the air. This technology is called “Visible Tungsten Energy Core (VTEC)”. Also, wide soles and a generous topline are apparent as you might expect from Big Bertha irons.


The Big Bertha B-21 irons come to retail on September 10, 2020 and have an MSRP of $899.99 USD (7-piece steel) or $999.99 USD (7-piece Graphite). The set composition is 4-PW with AW, SW, and LW being made available as well.

For more details, please see the press release below as shared by Jeff Newton (Global Communications Callaway Golf).


Until The Next Tee!!

We’ve designed our Big Bertha shaping with a new formula for distance and forgiveness. It’s a technology package that delivers more ball speed, higher launch and straighter shots for a new level of player confidence.

It features a confidence-inspiring shape that makes Bertha easy to hit, with generous offset, wide soles, and a thick topline. This is the first time that our A.I.-designed Flash Face Cup is in a Big Bertha Iron. We’ve created high balls speeds and increased spin robustness off of every club in the set, with a unique Flash Face architecture for each individual iron.


A.I. Flash Face Cup wasn’t the only first in this set. These irons also have a Visible Tungsten Energy Core (VTEC) which deepens the CG to make these irons incredibly easy to launch. We’ve also provided outstanding feel at impact from our proprietary urethane microspheres. These microspheres are strategically designed to absorb unwanted vibration without reducing speed. In short, you’re getting the iconic shaping that you want to see over the ball with incredible ball speed technologies to get the absolute most out of your swing.

Features & Benefits

Fast Ball Speeds From The First A.I.-Designed Big Bertha Iron – Our industry-leading Flash Face Cup in each club. We’ve created high ball speeds and increased spin robustness off of every iron in the set with a sophisticated face architecture that’s unique to every loft. Ball speed is further enhanced by our 360 Face Cup that flexes and releases at impact.


Amazing Forgiveness From Legendary Big Bertha Shaping –  This club profile that golfers love is engineered to give you more confidence over the ball with noticeably wider soles. For easy launch, lower spin and straighter shots, we’ve added more offset. Combined with our Flash Face Cup, we’ve developed a new formula for distance and forgiveness.

Higher Launch From Our Visible Tungsten Energy Core – We’ve added a significant amount of custom tungsten weighting. So we can deepen the CG in each iron with extraordinary precision, while still maintaining ball speed in the Flash Face Cup. Now you can get higher launch conditions through the set.

Pure Feel From Urethane Microspheres – Our patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
