What Srixon says about the ZX4 Mk II Irons:

“ZX4 Mk II Irons present game improvement forgiveness for mid to high-handicap players.

“Behind the irons’ sleek address looks and premium forged feel is maximum forgiveness plus powerful distance. And it’s all thanks to a hollow head design with extra-strong lofts.

“Featuring a narrow topline, moderate sole width, our longest blade length, and our highest offset.

“New ZX Mk II Irons are a culmination of fast and pure. A pure feeling at impact, for purer strikes, and a pure sound. With tech-driven ball speed in every number, energizing every shot.

“MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of ZX4 Mk II irons.

“MainFrame not only boosts COR, it also repositions mass away from the face and into the toe and sole for a lower Center of Gravity.

“This creates more than just faster ball speed, but also more consistency and forgiveness, enhancing all aspects of your Iron play, shot for shot.”

The Tour V.T. Sole features a higher bounce on the leading edges to provides better ball striking from fairway, rough or sand traps.

The new design also features wide and shallow grooves on the longer irons (4-iron to 7-iron) while the grooves are narrower and deeper in 8-iron to wedges for more spin and control on approach shots.

The ZX4 Mk II irons have extra-strong lofts for increased distance and a more penetrating ball flight with specs of 4-iron (21 degrees), 5-iron (23 degrees), 6-iron (25.5 degrees), 7-iron (28.5 degrees), 8-iron (33 degrees), 9-iron (38 degrees), PW (43 degrees) and AW (49 degrees).
