The new model incorporates many of the technologies of the recently released ZX7 and ZX5 irons, while also blending a new level of forgiveness for the company with the looks and feel Srixon irons are renowned for, through the hollow body construction.

Unlike some other models in the same category, the ZX4 is hollow throughout the entire set to offer increased forgiveness and optimised centre of gravity (CG) in every iron, which is blended with a traditional look at address and mid-sized iron head.

High-density tungsten is incorporated in the long and mid irons to lower the CG for higher launch and more forgiveness that is aided by the company’s ‘MainFrame’ technology.

Created with artificial intelligence and machine learning, MainFrame is a variable face thickness pattern milled into the back of each iron face, which is forged from HT1770 steel, to increase ball speed across the entire hitting area.

Chosen for the ZX4 due to its strength and lightweight properties, the steel used in the faces increases flex at impact for ball speed gains, while the forging process and 431 steel body offer soft feel.

Designed for improved turf interaction through its unique grind and bounce, the ‘Tour V.T. Sole’ of the ZX4 is complimented sole notches that make a return to Srixon irons and enhance workability for better players without sacrificing forgiveness.

“The new Srixon ZX4 irons mark a new revolution in forgiveness for Srixon,” Srixon’s Director of Engineering Dustin Brekke said.
