Callaway Great Big Bertha Fairway Wood utilizes a titanium construction, Forged Carbon soles, and multi-material weighting to increase ball speeds and improve forgiveness. FEATURES & BENEFITS 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. 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 A Triaxial Carbon crown and Forged Carbon sole plate save significant weight vs. traditional steel. 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. Enhanced Ball Flight Control Great Big Bertha Fairway Woods come with an adjustable hosel to help optimize your loft, trajectory and control for even more versatility.
