MAINFRAME Created with human intelligence yet perfected by the artificial kind, MainFrame is a one-of-a-kind face design that increases ball speed on every shot. While our engineers set the parameters, our computers ran the simulations—thousands of them—until we had our fastest irons yet.

HOLLOW DESIGN ZX4's hollow design gives you enough forgiveness to strike the ball across the face while still enjoying high shots that fly straight and find their targets.

TOUR V.T SOLE The unique Tour V.T. Sole gives Srixon irons a leg up against the competition with smoother turf interaction and improved impact feel. The V-shaped sole glides smoothly through turf, even if you strike slightly behind the ball.
