The most forgiving all-stainless steel set of golf clubs we’ve ever made
The new Big Bertha Iron set takes forgiveness to new heights by integrating a set of clubs featuring the new i-brids – clubs designed to replace hard-to-hit long irons – and transitioning that set into traditionally shaped irons. 

i-brids
The clubs that blend the control and accuracy of irons with the forgiveness, distance and versatility of hybrids. The low, deep center of gravity (CG) helps get the ball in the air quickly and easily, and the extremely wide sole helps improve turf interaction. 

Super Game-improvement Mid and Short Irons
Designed for the ultimate in forgiveness in their oversize design with an increased offset, a large effective hitting area and a wide sole for exceptional turf interaction.

Fully Integrated Set Design
Seamless performance progression throughout the set provides consistent distance separation with optimal trajectories.

Callaway Golf Core Technologies
Extreme Notch Weighting redistributes more weight to the perimeter for a higher moment of inertia (MOI) and more stability. VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness; S2H2 increases discretionary weight by removing it from the hosel and repositioning it in the perimeter of the clubhead; 360-Degree Undercut Channel maximizes perimeter weighting by moving the CG lower and farther back.

Modified Tru-Bore Design
An advanced version of the original Tru-Bore Design, the polycarbonate tip plug at the end of the shaft dampens vibration for enhanced feel and performance.
