ZXiU Utility Irons are powerful long Iron replacements-even among tour pros-featuring signature Srixon feel, higher launch, and excellent forgiveness in a blade-like design with moderate offset. i-FORGED Condensed Forging stretching from the high-toe area and along the topline of the Iron blade enhances overall strength, durability, and feel. Then the forged faces on ZXiU are softened to improve this already exceptional feel. MAINFRAME iQ MainFrame iQ is a variablethickness network of grooves, channels, and notches precisionmilled into the back of every ZXi5, ZXi5+, and ZXiU Utility Iron face. At impact, these features flex together to maximize energy transfer for more speed, more consistently, across the face. TOUR V.T. SOLE Srixon's Tour V.T. Sole takes turf interaction to a whole new level of detail with a proprietary combination of sole widths, bounce angles, and notches. This technology encourages a smooth glide through fairway, rough, and sand without losing speed, even if you enter the turf slightly behind the ball. REFINED PLAYERS SHAPING Guided by Srixon's tour staff, every new ZXi Iron has been refined for a cleaner, more exacting profile, featuring slightly thinner toplines than the previous generation. PRECISION FORGING BY ENDO Every new ZXi Iron face and body are forged at Japan's premier forging house: Endo, the gold standard in Iron forging. A place that refuses to compromise on feel.
