REVEALED: Srixon ZX4 irons are brand's most forgiving yet

Published:

Srixon's ZX4 irons mark a "new revolution in forgiveness" for the golf brand with artificial intelligence used to develop unique and fastest face pattern.

The new ZX4 irons bring forgiveness to the Srixon 2021 iron line-up while maintaining the brand’s signature look and forged feel.

Hollow from short to long iron, the ZX4 irons are designed to produce a straight and high launch right across the face. Premium, high-density tungsten in the base of the long and mid irons lowers their centres of gravity significantly, producing a high-launch profile.

Srixon's ZX4 irons are the brand's most forgiving set ever.

A forged HT1770 Steel face is strong and light, increasing face-flex at impact for enhanced speed and distance. And a 431 Steel body absorbs vibrations for softer feel.

ZX4 also feature Srixon’s new MainFrame technology, a one-of-a-kind face design that increases ball speed on every shot. Milled into the backside of each ZX4 face, MainFrame is a variable thickness pattern made up of grooves, channels, and cavities.

This pattern maximizes COR (energy transfer between face and ball) for more ball speed and enhanced distance.

The engineering team used artificial intelligence and machine learning to develop the unique face pattern, with computers running thousands of simulations before settling on the fastest design.

The unique Tour V.T. Sole gives ZX4 smoother turf interaction and improved feel. The V-shaped sole is designed to glide smoothly through turf, even if you strike slightly behind the ball.

Like all ZX irons, ZX4 also feature the resurgence of Srixon’s popular sole notches. Revered by professional tour players, these heel and toe notches enhance iron workability without sacrificing forgiveness.

“The new Srixon ZX4 irons mark a new revolution in forgiveness for Srixon,” says Joe Miller, Product Manager at Srixon Sports Europe.

“The irons include a fully hollow construction with wide soles for getting the centre of gravity extremely low and providing maximum forgiveness from the turf.

"The ZX4 irons accomplish this in addition to MainFrame technology, Tour V.T. Soles, tungsten weighting, and the look and feel expected with Srixon ZX irons.”
