The Callaway Big Bertha 19 Men's Hybrid has a combination of Jailbreak Technology ball speeds and adjustability for easy launch. Jailbreak Technology uses two inner bars behind the face that attach the crown and sole of the club head to strengthen the body and put more force load on the face for accelerated speed and more range. The Ultra-thin 455 stainless steel face connected with Hyper Speed Face Cup technology for racing speed and long range at extra impact locations across the face. It also has an OptiFit hosel system which is shorter and lighter allowing for an entirely optimized focus of gravity along with adjustability to custom fit your launch.
