A breakthrough innovation called Jailbreak Technology dramatically increases distance by stiffening the body to transfer more energy to the ball. And no one else has it. 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.Faster Head Speed from Industry-leading Aerodynamics: Streamlined head incorporates our proprietary Speed Step, created with direct input from aerospace experts, to improve airflow for more swing speed and distance.More Forgiveness and Lower Spin from Exo-Cage Construction: Innovative head construction unites our titanium Exo-cage with an ultra-light triaxial carbon crown and sole, allowing improved perimeter weighting for more forgiveness and makes it possible to position the CG in line with the neutral axis, which lowers spin.
