Callaway's new Great Big Bertha Irons are the titanium iron reinvented--Their first ultra-premium multi-piece, titanium design. They are combining driver-like power with the precision of an iron. By combining our titanium face and body with up to 145g of tungsten, they’ve reached a new level of speed, forgiveness, and overall performance. This multi-material construction creates lightweight power for effortless distance and control.
- Lightweight Power from a Forged Titanium Face and CP Titanium Body: By leveraging materials that are typically reserved for drivers, they’ve generated up to 96g of discretionary weight, and precisely repositioned this saved weight to increase launch and forgiveness. The Commercially Pure Grade (CP) 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 it the deepest center of gravity they’ve ever achieved in an iron
- 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: The patented urethane microspheres enhance sound and deliver a softer feel, while still allowing the face to flex for more ball speed
