Callaway Big Bertha OS Iron
Callaway Big Bertha OS Irons promote more distance in an entirely new way, led by extraordinary light and strong Exo-Cage that allows for strategically position weight to increase forgiveness, and helps the industry-leading, next-generation 360 Face Cup produce even faster ball speeds and more distance.
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 the 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.
Packed with technology and innovation, the new Big Bertha OS Irons offer premium performance for golfers seeking to get the most out of their game.
