ZX5 MKII irons combine premium forged feel and razor sharp looks with advanced power, speed and distance. MainFrame technology features a variable thickness pattern of grooves, channels and cavities that are milled into the back of the face for maximum flex during impact. Now available in an all-black Limited Edition black chrome finish that brings bold style to your bag. The 3i through 7i feature wider grooves that are ideal for longer shots in any course condition, while the 8i through AW have deeper, closer grooves to minimize turf interaction and optimize spin for approach shots. The Tour V.T. Sole is built with a proprietary combination of sole widths, bounce angles and notches that generate a smooth glide through any turf, rough and sand to allow you to strike the ball confidently and solidly without sacrificing speed. ZX5 MKII brings players distance in a cavity back iron package with wider soles and moderate blade length and offset.
