The Callaway Big Bertha Transition Iron is their easiest to launch club with incredible forgiveness due to their groundbreaking Hollow Body Construction making it the ideal super game-improvement iron. 

Easy launch, distance, and incredible sound and feel from the Hollow Body Construction
The Hollow Body Construction is the engine of the new Big Bertha irons. This revolutionary new construction suspends the MIM’d Tungsten weight using our proprietary urethane microspheres. It’s designed to deliver easy launch; long consistent distance; and incredible sound and feel. 

Long and consistent distance from the club face

The innovative 360 Face employs a flexible rim around the face that flexes and releases at impact to increase ball speed. And by using the high launch angles generated by the Hollow Body Construction, Callaway have made their thinnest face cup for increased speeds that promote longer distance.

Premium Design

The Big Bertha Transition Iron has an unforgettable look with its clean finish.

The steel stiff flex shafts in these clubs are +1.5" over standard length for true hybrid distance
