Great Big Bertha Epic Sub Zero Driver

New for 2017 Callaway Epic with the Revolutionary JailBreak technology 

What makes it Epic?

Epic's power is based on our innovative new Jailbreak Technology, which fundamentally changes the way the head and clubface behave at impact to deliver more ball speed and distance. The key structural components of a metalwood – crown, sole and face – each bend, flex and rebound at impact. Because they’re connected, they influence each other's dynamics. Jailbreak Technology creates a remarkably efficient relationship between these components to promote more ball speed across a much larger area of the face.

Jailbreak positions two ultra-light (3g), strong titanium bars behind the face, parallel to each other and connected on either end to the crown and sole. The size, strength and position of each Jailbreak bar work together to reduce how much the crown and sole deflect, forcing the face to take on more of the load created at impact than ever before. This results in faster ball speeds across the entire face from swing to swing, promoting more distance.

Features & Benefits

Increased Distance from Jailbreak Technology
A breakthrough innovation which dramatically increases distance by stiffening the body to transfer more energy to the ball.   

Maximum Forgiveness from Exo-Cage Construction
Innovative head construction that unites our aerospace-grade titanium Exo-Cage outfitted with an ultra-light triaxial carbon crown (9.7g -- lightest ever in a Callaway driver) and sole (5.8g) allows us to distribute more weight in the perimeter for higher MOI and more forgiveness in a high-launch, low-spin design.

Precision Shot-shape Control from Adjustable Perimeter Weighting
Changing the position of the 17-gram weight on the precision-engineered track allows you to easily fit the club to your swing, providing 21 yards of shot-shaping control to promote straighter and longer tee shots.

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.

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.

Four High-Performance Stock Shaft Options
Diamana M+ Green, Project X HZRDUS, Fujikura Pro Green and Aldila Rogue Max in five weight classes: 40g, 50g, 60g, 70g, 80g. Each premium, tour-proven shaft enables fitting to dial in performance for every player through correct weight, torque and flex profile choice.
