Callaway Great Big Bertha Irons

Callaway’s first multi-piece titanium and tungsten iron provides driver-like power with the precision of an iron.

Features of the Callaway Great Big Bertha Irons

Forged Titanium Face and CP Titanium Body

By leveraging materials that are typically reserved for drivers, Callaway generated up to 96g of discretionary weight, and precisely re-positioned this saved weight to increase launch and forgiveness. The Commercially Pure Grade Titanium body flexes more at impact than traditional steel and works together with the thinner face to transfer more energy to the ball.

Tungsten Speed Cartridge

The Tungsten Speed Cartridge features up to 145g of high-density tungsten, which provides increased speed and launch by giving the deepest center of gravity ever achieved in a Callaway iron. This unmatched level of tungsten is a 133% increase over Rogue ST Max.

A.I. Designed Face

The forged titanium face is optimized to increase speed and improve spin consistency. Great Big Bertha is the first Callaway iron to combine titanium and industry-leading A.I. technologies for optimized performance.

Urethane Microspheres

Callaway’s patented urethane microspheres enhance sound and deliver a softer feel, while still allowing the face to flex for more ball speed.
