Callaway Great Big Bertha Fairway Wood The Great Big Bertha fairway woods provide exceptional ball speed and forgiveness from a uniquely designed titanium face and body. Typically reserved for drivers, titanium provides significant weight and strength advantages over a traditional steel fairway wood, leading to increased distance. The industry-leading, A.I. designed titanium face cup and Jailbreak with Batwing Technology work together to enhance speed across the face. In addition, the Triaxial Carbon Crown and Forged Carbon Sole reposition weight to areas where it is most effectively used for increased forgiveness and launch. Lightweight Power from a Titanium Face & Body Usually reserved for drivers, titanium provides Great Big Bertha with a significant weight and strength advantage compared to a traditional steel fairway wood. By leveraging a titanium face and body, 53% of the total head weight is made up of discretionary weight. This weight savings enables us to create a larger, more forgiving footprint and an ultra-low CG that steel does not allow. Fast Ball Speed from A.I. Designed Titanium Face Cup & Jailbreak with Batwing Technology The titanium face is uniquely optimized for each fairway wood head through A.I. for enhanced ball speed and spin consistency in a powerful design. Our Jailbreak with Batwing Technology pushes stiffness to the perimeter, while still allowing the face to flex for high ball speeds across the face. More Forgiveness from Multi-Material Construction Great Big Bertha creates exceptionally high forgiveness. It starts with a lighter, stronger triaxial carbon crown that saves a significant amount of weight. The Forged Carbon sole also aids in weight savings and relocates the CG to create a slight draw bias. With all this discretionary weight, our engineers leveraged 50g of internal tungsten and a 15g steel plate on the sole to create an easier, higher launch. Premium Ultra-lightweight Components An ultra-premium UST Helium Nanocore Shaft, combined with a Winn Dri-Tac Lite Grip make the club easy to swing while the adjustable hosel allows the golfer to dial in launch.
