Innovative Jailbreak With OptiFit Adjustability

The Big Bertha clubs are the first hybrids ever to combine innovative Jailbreak Technology with adjustability for fast ball speeds, long distance, and easy launch.

With long distance & fast ball speeds, the revolutionary Jailbreak Technology incorporates two internal bars that stiffen the body, placing more impact load on the face to promote fast ball speed and long distance. The ultra-thin Carpenter 455 steel face is extremely fast. Combine that with the Hyper Speed Face Cup that promotes fast speeds across the face for longer distance on off-centre hits.

For the first time ever in a hybrid, Callaway have combined Jailbreak with adjustability. The new OptiFit hosel system lets you easily choose from eight loft and lie settings to dial in the launch angle and shot shape that promote maximum distance and accuracy with your swing. Loft can be set to -1°, S (Stated), +1°, +2°. Face angle can be set to Neutral or Draw.

With progressive head shapes, they are both forgiving and appealing as you down up in lofts. Fitted with UST Recoil shafts for lightweight performance to increase ball speeds.
