The Callaway Big Bertha B21 Irons are the first Big Bertha irons designed using Artificial Intelligence (A.I.). Callaway designed their 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 Callaways 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 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. Callaway have also provided outstanding feel at impact from their 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.
