Callaway Big Bertha OS Irons

Big Bertha OS irons incorporate a revolutionary clubhead construction, called the Exo-Cage that promotes more distance in an entirely new way.

How? The ExoCage’s extraordinary combination of strength and light weight allows Callaway engineers to distribute more discretionary weight into strategic locations to promote more forgiveness and to allow our next-generation 360 Face Cup technology to function more efficiently.

The result is more ball speed across the face to give you more distance on every swing.

Features & Benefits


Distance Features

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 centre of gravity to promote a higher launch angle for longer carry and more ball speed on hits low on the face.


Control Features

Progressive Centre 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.
