AI-designed MainFrame faces and weighting, along with our legendary ZipCore technology, combine to deliver all of the power, control, and confidence you need to hit it far and stick it close without fail.
Oh, and did we mention they look darn good
XL HEAD DESIGN
A bigger head allows us to position more mass away from the center of the club for more MOI. That MOI boosts forgiveness to levels that help all your shots launch high and fly straight.
HYDRAZIP
Our proprietary dynamic blast and laser-milled line system creates roughness to enhance friction, optimizing spin for distance with long Irons and control with short Irons.
MAINFRAME
MainFrame in the 4i–7i is a system of channels and cavities carefully milled into the backside of ZipCore XL Iron faces to maximize flex at impact. Boosting COR while also repositioning mass for a lower CG, MainFrame creates faster ball speed plus more consistency and forgiveness.
