The uniquely light-and-strong design of the EXO-CAGE allows more weight to be positioned in strategic locations to increase forgiveness while also helping our next-generation 360 Face Cup technology to function more efficiently
Next-generation 360 Face Cup technology elevates clubface COR closer to the USGA limit to produce even faster ball speeds and more distance
Tungsten-Loaded Standing Wave technology in the sole lowers the center of gravity to promote a higher launch angle for longer carry and more ball speed on hits low on the face
Progressive Center of Gravity technology entails moving the CG location progressively lower in each head from the highest-lofted to the lowest-lofted, promoting higher launch and long carry in the long-irons and increased control in the short-irons
Women's and Senior models are engineered to be lighter in overall weight
