Callaway Great Big Bertha Epic Sub Zero Fairway Wood

Increased Power and Forgiveness from Triaxial Carbon Crown: Incredibly light and strong triaxial carbon crown -- 78% lighter than a steel crown -- frees up immense weight used to increase MOI and lower the CG for easy launch and extremely long carry.
High Ball Speeds from Next-Gen Hyper Speed Face Cup: Fourth generation Hyper Speed Face Cup responds to off-center hits with greater efficiency to promote faster speed across more of the face.
Faster Head Speed from Industry-leading Aerodynamics: The streamlined head incorporates our proprietary Speed Step, created with direct input from aerodynamics experts at Boeing, to improve airflow to encourage more swing speed and distance without extra effort.
Spin and Trajectory Control from Adjustable Weighting: Switching the positions of the 22g and 3g weights adjusts spin +/- 350-400 rpm to create a choice between lower launch, spin and trajectory or higher launch, spin, and trajectory.
OptiFit Adjustability: An OptiFit Hosel allows for further fine-tuning in the fitting process to aid precise shot-shaping and adjustment of lofts up and down if required.
