Who’s It For?

Callaway’s Big Bertha products have been exceptional over the years in providing game-improvement performance for golfers that are looking for some extra forgiveness and high launch. New in 2020 is the Callaway Big Bertha B21 line, which is designed with some of Callaway’s newest innovations to drive fast ball speeds, easy launch, and supreme forgiveness. The Big Bertha B21 irons are a great fit for mid- to high-handicap golfers seeking better performance in an easy-to-hit package.

The Tech Story

Callaway is one of the leading golf equipment manufacturers because of its impressive innovation year after year. In 2020, Callaway built the Big Bertha irons with Flash Face technology, designed with Artificial Intelligence, so golfers will get more ball speed with contact made all over the clubface, not just in the center. The Bertha shaping includes noticeably wider soles and increases offset in order to bring the center of gravity down and improve launch. Additionally, Callaway added tungsten weighting to the Tungsten Energy Core in an effort to deepen the center of gravity even more while maintaining ball speed generated by the Flash Face Cup. And finally, patented urethane microspheres have been packed into the clubhead to absorb unwanted vibrations for superb feel.
