FIRST LOOK: CALLAWAY BIG BERTHA OS HYBRID

The iron is a super game improver, aimed at higher handicap golfers.

Features

Exo-Cage

The 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.

360 Face Cup

Next-generation 360 Face Cup technology elevates clubface COR closer to the USGA limit to produce faster ball speeds and more distance.

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 Centre of Gravity

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.

Women’s and Senior models

Women’s and Senior models are engineered to be lighter in overall weight and with more loft to promote faster ball speed and higher launch angle to make it easy to get the ball in the air.
