Callaway Big Bertha Fusion

The Big Bertha Fusion driver pushes the boundaries of forgiveness like no Callaway club ever has with its revolutionary design. The driver features EXOCAGE which is an aerospacegrade titanium exoskeleton. The rest of the club head is made with ultrastrong triaxial carbon. This unique fusion of materials increases the drivers forgiveness on mishits because it raises the moment of inertia MOI. To further improve the accuracy of offcenter ball strikes Callaway has strategically placed 35.4 grams of weight into areas of the club head that optimize the center of gravity. The Big Bertha Fusion driver also features enhanced aerodynamics for faster club head speeds with Callaways Speed Step technology. Standard length drivers are 45.5. 44.5 is available through custom only.
