Callaway Big Bertha Fusion Driver - 44.5"
The Big Bertha Fusion Driver is a material change in forgiveness and distance, led by our revolutionary titanium Exo-Cage and ultralight triaxial carbon crown, with a new and innovative shape, and industry-leading aerodynamics.
Maximum Forgiveness from Fusion Technology
Big Bertha Fusion pairs an aerospace-grade titanium Exo-Cage with our ultra-light triaxial carbon crown and sole. The fusion of these materials allowed Callaway engineers to position substantially more weight in the perimeter and far back from the face compared to our previous drivers, resulting in a dramatically higher level of forgiveness.
Speed and Forgiveness from a New and Innovative Shape
Big Bertha Fusion’s triaxial carbon Exo-Cage gives us the freedom to break previous tradeoffs regarding head shape, giving us the ability to create an appealing new shape that combines fast aerodynamics with high MOI. The new shape also gave us new options in acoustic engineering, allowing us greater ability to evoke an especially satisfying sound and feel.
Increased Head Speed from Industry-leading Aerodynamics
The streamlined head shape, aided by our proprietary Speed Step that we created with the help of aerospace experts, is designed to move faster through the air.
Two High Performance Stock Shaft Options
UST’s first ever Recoil driver shaft is designed to load energy on the downswing and unload with an extraordinary combination of power and precision through impact.
Mitsubishi’s Diamana Red shaft combines a firm midsection and active tip to promote high launch, low spin and fast ball speed, and to make it easier to hit a distance-enhancing draw.
Available in stock 44.5” and 45.5” lengths.
