The most untraditional traditional-looking irons you’ll ever play.
The next generation of tools to take apart any course. Big Bertha Fusion Irons incorporate superior weight-shifting Fusion Technology and three distinct materials. The unique head shape provides a clean, refined look and unprecedented performance, yet provides the playability and confidence at address once reserved for oversize irons. It's another patented breakthrough, deeply rooted in our relentless endeavor to create the most scientifically advanced equipment for your game.
Fusion Technology in irons.
At their heart is the patented Tunite alloy cradle. Created by Callaway Golf engineers, this ultra-dense material allows the repositioning of an unheard-of 77 percent of the clubhead's mass to its perimeter, giving you exceptional stability. With no twisting or turning, balls fly straighter off the club.
The lightweight titanium face is 35 percent lighter than a comparable steel face, allowing more mass to be moved to the club perimeter for forgiveness and increased effective hitting area.
The TPU SenSert is an exclusive, chemically engineered material that reduces vibration at impact and produces a crisp, responsive sound and unmatched feel.
