Callaway Great Big Bertha Driver [Hand: MRH][Loft:10.5 DEG][Flex:REG]

A MATERIAL DIFFERENCE IN PERFORMANCE: An ultra-lightweight chassis and easy-to-swing design to increase club head speed and overall distance.

Legendary Great Big Bertha Distance from an Innovative, Lightweight Design: This easy-to-swing driver is engineered with an ultra-lightweight design for unmatched distance characteristics. It’s nearly 30g lighter than a tour driver and an ideal option for golfers who want to increase their swing speed.

Forged Carbon Sole & Triaxial Carbon Crown Increase MOI: Engineers paired a lightweight Triaxial Carbon Crown with a Forged Carbon Sole to increase MOI. With all this discretionary weight, our engineers moved the CG lower and deeper to enhance forgiveness, while the steel sole plate makes it easier to hit a draw.

High Ball Speeds from Jailbreak Speed Frame: The Jailbreak Speed Frame is powered by A.I. for enhanced horizontal and torsional stability. All this stability promotes increased ball speed across the face.

Lower Spin from an A.I. Designed Flash Face: Sspin optimisation in the industry-leading A.I. face technology. The new formula increases ball speed while lowering spin to increase total distance.

Shaft: UST Mamiya Helium Nanocore IP 50 Graphite
