Big Bertha OS Irons promote more distance in an entirely new way, led by extraordinary light and strong Exo-Cage that allows the club to strategically position weight to increase forgiveness, and helps Callaway's industry-leading, next-generation 360 Face Cup produce even faster ball speeds and more distance. 

Features + Details

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 our 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 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 for Increased Control

 

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

 

Lighter in overall weight, with more loft to promote faster ball speed and higher launch angle to make it easy to get the ball in the air.
