Loft progression
About the Yonex EZONE GS i-Tech
The EZONE GS i-Tech succeeded the EZONE GS as Yonex's international-market game-improvement iron, reviewed by Golf Monthly in February 2023. It keeps the GS line's four-piece graphite-hybrid head - a cast mild-carbon-steel body, a maraging steel face, a tungsten plate low in the head and Yonex's signature carbon graphite insert damping vibration between the metals - and adds a "G-Brid" face design that flexes inward at impact, cutting head weight by roughly 20% to lower the centre of gravity for a higher, faster launch, plus a Groove Flow Concept that angles the grooves rather than cutting them straight across for straighter ball flights. Lofts are essentially unchanged from the EZONE GS, with a 29-degree 7-iron and a 43-degree pitching wedge across a 4-iron-to-sand-wedge factory range. A six-piece set retailed at £749 in the UK with either Yonex's own EX-GO2 graphite or Nippon N.S.Pro Modus3 Tour 120 steel in the fitting matrix.

Frequently asked questions
What is the loft of a Yonex EZONE GS i-Tech 7-iron?
The Yonex EZONE GS i-Tech 7-iron has a loft of 29 degrees, a lie of 62.5 degrees and a length of 37.5 inches.
What does the G-Brid face do on the EZONE GS i-Tech?
It lets the face flex inward at impact, which Yonex says cuts head weight by about 20% and lowers the centre of gravity for a higher launch and more ball speed.
How does the EZONE GS i-Tech differ from the original EZONE GS?
The head keeps the same four-piece graphite-hybrid construction and a nearly identical loft ladder, but adds the flexing G-Brid face and an angled Groove Flow Concept aimed at straighter ball flights.
Production status
Introduced in 2023, the Yonex EZONE GS i-Tech has no confirmed end date on file. It replaced the Yonex EZONE GS. LoftChart records a discontinuation year only where a source dates it, and none has been found for this set, so it may or may not still be in the Yonex catalogue — check with Yonex or a retailer before counting on a new set. Used sets appear on eBay, and should be measured against the chart above before buying, since irons are routinely bent from standard.
