2023 Callaway Great Big Bertha Iron Set

[tab name="Description"]

A MATERIAL DIFFERENCE IN PERFORMANCE

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

• Lightweight Power from a Forged Titanium Face and CP Titanium Body
  By leveraging materials that are typically reserved for drivers, we’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 us the deepest center of gravity we’ve ever achieved in an iron. This unmatched level of tungsten is a 133% increase over Rogue ST Max, and the most ever in a Callaway 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
  Our patented urethane microspheres enhance sound and deliver a softer feel, while still allowing the face to flex for more ball speed.
