Maximum Forgiveness from Fusion Technology: Big Bertha Fusion pairs Callaway's ultra-light triaxial carbon crown, thats 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 their previous fairway woods, resulting in higher launch and more forgiveness. Forgiveness & Power From a New Shape: The triaxial carbon gives Callaway the ability to break previous tradeoffs regarding head shape, allowing them to create an appealing new shape with extremely high MOI. The new shape also presented new options in acoustic engineering, with more freedom to evoke an especially satisfying sound and feel. High Ball Speeds from Callaway's Face Cup: Callaway is serious about giving you the most distance in a fairway wood, which is why they've put in their industry-leading Hyper Speed Face Cup. Its designed for high speeds that make the ball fly farther on center hits and off-center hits. Grip: Golf Pride New Decade - Platinum/Black
