Very Forgiving and Long
Big Bertha OS Irons promote more distance in an entirely new way, led by extraordinary light and strong Exo Cage that allows Callaway to strategically position weight to increase forgiveness, and helps their industry leading, next generation 360 Face Cup produce even faster ball speeds and more distance.
More Forgiveness and Ball Speed from New Exo-Cage Technology
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 their next generation 360 Face Cup technology to function more efficiently.
Even More Ball Speed from Next Gen 360 Face Cup
Next generation 360 Face Cup technology elevates clubface COR closer to the USGA limit to produce even faster ball speeds and more distance.
Higher Launch for Longer Carry from Tungsten Loaded Standing Wave
Tungsten Loaded Standing Wave technology in the sole lowers the centre 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 for Increased Control
Progressive Centre 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.
