Callaway Golf 2017 Men’s Great Big Bertha Epic Sub Zero Driver
Innovative new technology changes how the head and face behave at impact to promote more speed across a larger area of the face for increased average distance
Innovative combination of Titanium exo-cage and triaxle carbon crown (lightest EVER in a Callaway driver) and sole create unprecedented forgiveness in a high-launch, low-spin design
Two interchangeable weights in the head (2g and 12g) to adjust spin-rate and launch angle. Put the 12g up front to lower spin; in back for higher launch and higher MOI
Streamlined head incorporates our proprietary speed step, created with Direct Input from aerospace experts, to improve airflow for more swing speed and distance
Four high-performance Stock shaft options – hazards, diamana, Fuji, and rogue in four weights. Each premium, Tour-proven shaft is engineered to promote speed, power, stability, feel and control
