Additional Information

Big Bertha B21 Hybrid

Distance Any Way You Swing It

The Big Bertha B21 Hybrid is built for the players who want to unlock their inner distance with a total forgiveness package. This is Callaway's easiest to launch hybrid with a larger head volume, and it’s designed to help you get rid of the big miss that spins off line. When you hit it straighter, you hit it longer…it’s just that simple.

Let’s start with the industry-leading ball speed technologies that help you get all that distance. They're giving you fast speeds across a more expansive area of the face with their A.I. designed Flash Face SS21. For even more speed their innovative Jailbreak Technology connects the sole and crown, which allows the face to take on more of the load at impact. So your shots are going to go a long way, even if you don’t make perfect contact.

To hit the ball straighter Callaway increased the offset. This helps to square the club at impact. To enhance your launch and trajectory, they incorporated dual MIM’ed (Metal-Injected Molding) Tungsten weights into the sole of the clubhead. And to provide even more forgiveness, they engineered their T2C Carbon Crown for higher MOI and easy launch.

Big Bertha gives you the performance technologies you need with a forgiving shape and increased offset. If you’re looking for more confidence and more distance any way you swing it, then you’ve come to the right place.

Fast Ball Speeds From Flash Face SS21

Fast ball speeds across an expansive area in each model and loft, with our advanced A.I.-designed Flash Face. So you’ll hit it long, even if you miss the center of the face at impact.

AI Face

Straighter Ball Flight From Increased Offset

We’ve added more offset to help reduce your slice or big miss. This increased offset helps to promote a straighter ball flight for more distance.


Enhanced Launch and Trajectory Control From Dual MIM’ed Tungsten Weighting

Optimized CG for launch and stability from precisely shaped dual MIM’ed tungsten weight.

Increased Ball Speed And Easy Launch

Fast ball speed from two internal Jailbreak bars that connect the sole and crown, so the face can take on more of the load at impact. And to create higher MOI in a forgiving shape, we’ve used a significantly lighter carbon crown that allows us to redistribute weight.

Premium Components

Features a completely new RCH shaft, designed by Callaway to specifically enhance the Big Bertha offering, with an Active Tip Flag section for easy launch. And it comes stock with a Golf Pride Tour Velvet Soft Grip.

Big Bertha B21 Irons

The First Big Bertha Iron Designed Using Artificial Intelligence. For Distance Any Way You Swing It.

You’re looking for more distance, and these irons are here to give it to you. In fact, Callaway designed their legendary Big Bertha shaping with a NEW formula for distance and forgiveness…any way you swing it. It’s a technology package that delivers more ball speed, higher launch and straighter shots for a new level of confidence that you didn’t think was possible.

It all starts with the confidence inspiring shaping that makes Bertha so easy to hit. Generous offset, wide soles and a thick topline inspire confidence. But there’s even more under the hood.

This is the first time that their A.I.-designed Flash Face Cup is in a Big Bertha Iron. They have 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…these irons also have a Visible Tungsten Energy Core (VTEC) which deepens the CG to make these irons incredibly easy to launch. Callaway has 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.
