Big Bertha B21 Steel Irons

Callaway Big Bertha B21 Irons - Steel Shafts

You’re looking for more distance, and these irons are here to give it to you. In fact, Callaway have designed the 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 Big 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 the A.I.-designed Flash Face Cup is in a Big Bertha Iron. Callaway 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 have also provided outstanding feel at impact from the 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.
