With Srixon’s PureFrame, it’s now possible to get an even more solid feel on off-center strikes. The frame is a key design feature of the new ZX MKII iron line, which consists of four models — the ZX4, ZX5 and ZX7.
INNOVATIVE TECH
In addition to PureFrame, Srixon retained several of its key technologies from the first generation ZX, including Mainframe and the Tour V.T. sole.
CONSISTENT LOOK
Every iron in Srixon’s 2023 ZX MKII lineup has the similar topline thickness, making it a cinch to mix and match models.
The hollow cavity on the ZX4 is going to make it easier to chase distance, especially when paired with a red-hot HT1770M steel face.
NEW LOOK
This iron offers the longest blade length in the set and a generous sole width. While those attributes might turn some golfers off, the sleek curves make it look visually appealing in the address position.
CONSISTENCY
The ZX4 is a great option for golfers who struggle with consistent contact but don’t necessarily want to go up in head size to solve the problem.
Workability can be found in the ZX7, making it a strong choice for better players.
COMPACT PROFILE
Great for players who need a more compact profile in the short irons of a blended set.
SOLID CONSTRUCTION
The solid construction head is forged from 1020 carbon steel with a slug of tungsten placed in the toe of each long and mid-iron to maintain a consistent ball speed and spin rate on mishits.
For years, unwanted vibrations were part of the iron package for golfers playing better-player models. Center-face contact elicited a solid feel at impact. But anything around the heel or toe left much to be desired in terms of feel and consistency.
Thanks to innovations like Srixon’s PureFrame, it’s now possible to get a more solid feel on off-center strikes. The frame is a key piece of technology for the new ZX MKII iron line, which consists of four models — the ZX4, ZX5, ZX7 and ZX utility. Forged into the body of the iron directly behind the sweet spot is a raised area of 1020 carbon steel that’s 80 percent thicker.
Designers have added more material behind the hitting area in the past to improve feel, but rarely to this extent. With the ZX4, ZX5 and ZX7, the end result is a solid, soft feel at impact across where golfers need it most. (It should be noted each model has a different cavity design.)
