The Srixon ZXi4 Irons (Steel Shaft) have a clean look at address, forged feel, and hollow head design. This softer material also allows us to adjust loft and lie more easily to ensure all ZXi4 players receive the perfect fit.; MAINFRAME MainFrame is a variable-thickness pattern of grooves, channels, and cavities carefully milled into the backside of the iron face that maximises flex at impact for higher ball speeds. For this generation of MainFrame, they've saved additional weight by expanding the milled toe notch, resulting in a deeper centre of gravity. This third-generation design amplifies ball speed and adds the right amount of forgiveness.; 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.; PROGRESSIVE GROOVES The 4i-7i feature wide grooves, ideal for longer shots in all conditions. The 8i-SW have deeper, closer-set grooves that cut through grass and debris to enhance spin on approach shots. Laser milling between each groove on every loft enhances friction in all conditions. This approach creates remarkable congruency across the Iron Set as spin, distance, and launch window remain as consistent as possible.; PLAYERS-INSPIRED IRON SHAPES Moderate sole width, our longest blade length, and our highest offset maximise the forgiveness of ZXi4 hollow irons while still offering an appealing look at address. Every ZXi Iron features the same topline thickness, creating an identical look at address for seamless blending of models.; HOLLOW DESIGN Hollow from short to long irons, ZXi4 is the most forgiving model in the ZXi Iron Series-offering the freedom to strike the ball across the face while still enjoying shots that feel great, launch straight, and find their target. A new double bore in the hosel of ZXi4 allowed us to place more weight lower in the clubhead for a higher launch and more forgiveness.; Specifications: HANDICAP: Mid-High; FORGIVENESS: High; TRAJECTORY: Mid-High; WORKABILITY: Low-Mid; DISTANCE: Long;
