Meet the New Callaway Big Bertha OS Irons & Hybrids

The Big Bertha name is not something Callaway takes lightly. So trust that when they put the BB stamp of approval on a new product line, it earned it.

The new Big Bertha OS irons & OS hybrids are proof of that.


Built around the same technology as the new Big Bertha Fusion driver, the OS irons feature new Exo-Cage Technology. This weight-distribution construction technique allows designers to move mass to forgiveness-increasing strategic placements. Combined with a new 360 Face Cup technology, this design allows for maximum ball speed on mis-hits.

But more ball speed means nothing without proper launch, so Callaway utilized Tungsten-Loaded Standing Wave technology in the sole to keep the mass low, maximizing launch potential for shots that carry farther.

Players who prefer hybrids instead of long irons will be able to build their set with the new, matching Big Bertha OS hybrids.


A slightly larger head, Speed Step technology, and a next-generation Hyper Speed Face Cup are the highlight features of the adjustable hybrid line. Callaway engineers have pushed the face even further than in past models, getting ever-closer to the USGA’s COR limit. That’s an acronym-filled way to say that the balls really fly off the face.

The slightly deeper head means forgiveness has been upped as well, and the Dual Runner Sole has been engineered on the underside for better turf interaction, too.

Taking playability a step further, the Women’s and Seniors’ models of both the irons and hybrids have been designed to be lower in overall weight. Like most of Callaway’s offerings, premium shafts and grips will be available, so see a Golfsmith Master Club Fitter and get tuned in.

The Big Bertha OS hybrids and irons will be available at Golfsmith September 9th.
