Big Bertha Fusion pairs our ultra-light triaxial carbon crown, that’s 78% lighter than a typical steel crown, with a steel body. 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 fairway woods, resulting in higher launch and more forgiveness.
The triaxial carbon gives us the ability to break previous tradeoffs regarding head shape, allowing us to create an appealing new shape with extremely high MOI. The new shape also gave us new options in acoustic engineering, with more freedom to evoke an especially satisfying sound and feel.
We’re serious about giving you the most distance in a fairway wood, which is why we’ve put in our industry-leading Hyper Speed Face Cup. It’s designed for high speeds that make the ball fly farther on center hits and off-center hits.
