EQUIPMENT: Srixon Debuts ZX4 Irons to Complete ZX Lineup

Srixon has a bit of a cult following out there for its irons, dating back to 2014 and the Z 545/745/945 lineup. And with the recent release of the ZX5 and ZX7, Srixon has immediately had some success, with Brooks Koepka pulling off a come-from-behind win at the Waste Management Open after just putting the ZX7s in the bag (which helped him lead the field in Greens In Reg).

The ZX4 irons are a fully hollow set created to bring forgiveness to the Srixon iron lineup while maintaining the brand’s signature look and forged feel. The iron’s sharp address view and mid-sized profile give them a palatable shape, while their technologies produce exceptional performance.

The benefit of the hollow head, forged face combination means the ZX4 irons will give you the freedom to strike the ball across the face while still enjoying high shots that launch straight and find their targets. Premium, high-density tungsten in the base of ZX4’s long and mid irons lowers their centers of gravity significantly, producing a high-launch profile. A forged HT1770 Steel face provides enhanced speed and distance, while the 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 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.

Srixon’s unique Tour V.T. Sole gives the ZX4 smoother turf interaction, promoting a smooth glide through the turf, and improved impact feel.

Like all ZX irons, ZX4 also features the resurgence of Srixon’s popular sole notches. Revered by professional tour players, these heel and toe notches enhance iron workability without sacrificing forgiveness. Additionally, the uniform design philosophy throughout the ZX series means that players can seamlessly mix-and-match a combo set together, like ZX4 long (4-6) irons and ZX5 scoring (7-PW) irons.

“The new Srixon ZX4 irons mark a new revolution in forgiveness for Srixon,” says Dustin Brekke, Director of Engineering at Srixon. “The irons include a fully hollow construction with wide soles for getting the center 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.”

The ZX4 Irons officially launch in North America on March 5, 2021. Stock shaft options include the Nippon N.S. Pro 950GH Neo (Steel; Mid Launch) (Reg. Flex in 94.5g, Stiff Flex in Stiff), retailing for $1,300, and UST Mamiya Recoil 760/780 ES SmacWrap (Graphite; Mid/High Launch) (Reg. Flex in 70g, Stiff Flex in 87g), retailing at $1,400.
