Fusion Technology:

Callaway's Fusion Technology combines a stainless steel face, sole and body with a lightweight carbon composite crown to create maximum perimeter weighting for exceptional stability on off-center hits.

Lightweight Carbon Composite Crown:

The carbon composite crown is stronger and lighter than an equivalent stainless steel crown, creating additional discretionary weight which is placed low and into the perimeter of the clubhead for improved launch parameters and more resistance to twisting.

Stainless Steel Face:

The stainless steel face, sole and body utilizes Variable Face Thickness (VFT) technology, and is fused in place with the crown, providing an ultra-low, optimized Center of Gravity (CG) for higher ball speed, a strong, high ball flight and power in every shot.

High Moment of Inertia:

Big Bertha Fusion Fairway Woods have the highest Moment of Inertia (MOI) of any Callaway fairway woods, which produces the most stability and accuracy on off-center hits.
