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 Exo-Cage’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.

KEY FEATURES

BIG BERTHA OS IRONS

More Forgiveness and Ball Speed from New Exo-Cage™ Technology

Positions more weight in strategic locations to increase forgiveness and helps our next-generation 360 Face Cup function more efficiently.

Even More Ball Speed from Next Gen 360 Face Cup™

Elevates clubface COR closer to the USGA limit to produce even faster ball speeds.

Higher Launch for Longer Carry from Tungsten-Loaded Standing Wave

Technology in the sole lowers the center of gravity to promote higher launch for longer carry and more ball speed low on the face.

Progressive Center of Gravity for Increased Control

Moving the CG location progressively lower in each head promotes higher launch and long carry in long-irons and increased control in 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.

“We built Big Bertha OS Irons for golfers who want an easy-to-hit iron with game-changing distance”
