Callaway Great Big Bertha Irons

A Material Difference in Performance

This is the titanium iron reinvented–Callaway’s first ultra-premium multi-piece, titanium design. The power of a driver has been combined with the precision of an iron. By combining a titanium face and body with up to 145g of tungsten, a new level of speed, forgiveness, and overall performance has been reached. This multi-material construction creates lightweight power for effortless distance and control.

Lightweight Power from a Forged Titanium Face and CP4 Titanium Body

By leveraging materials that are typically reserved for drivers, 96g of discretionary weight has been generated and precisely repositioned to increase launch and forgiveness. The Great Big Bertha iron features the thinnest titanium face Callaway has ever used in an iron. On top of that, it’s also the lightest. The Commercially Pure Grade 4 (CP4) Titanium body flexes more at impact than traditional steel and works together with the thinner face to transfer more energy to the ball.

Speed and Launch from the Tungsten Speed Cartridge

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

A.I.-Designed Forged Titanium Face for Increased Consistency

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.

Patented Urethane Microspheres for Exceptional Feel

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