Callaway defined new boundaries to push past with the Callaway Big Bertha Fusion Driver. The combination of an aerospace-grade titanium EXO-CAGE and an ultralight triaxial crown and sole optimizes CG like never before, providing the ultimate in forgiveness, with the weight savings affording the especially satisfying sound and feel. Speed Step Technology partners with streamlined shaping to further enhance speed and launch, making the Fusion no slouch in the distance department.
Combines an aerospace-grade titanium EXO-CAGE with an ultralight triaxial carbon crown and sole
Triaxial carbon is 65% lighter than titanium and 35% thinner than Callaway's previous composite material
Affords substantially more weight (35 g) at the perimeter and far-back from the face for maximum forgiveness
Higher MOI (up to 17%) translates to greater stability at impact and straighter flight on off-center contact
