A new double bore hosel lets us position more weight low in the clubhead for higher launch and added forgiveness. Plus, the ZXi4’s hollow design allows for a sleek, sharp look at address, delivering all that forgiveness in a stylish, compact profile. MAINFRAME MainFrame’s variable-thickness grooves, channels, and cavities maximize flex for higher ball speeds. The expanded toe channel reduces weight and raises MOI, creating a lighter clubhead with a deeper center of gravity. This third-gen design boosts speed and adds balanced forgiveness. Tour V.T Sole Srixon’s Tour V.T. Sole redefines turf interaction with its unique blend of sole widths, bounce angles, and notches. This tech ensures a smooth glide through fairway, rough, and sand, maintaining speed even on shots that hit the turf slightly behind the ball. Progressive Grooves The 3i-7i irons have wide grooves for long shots in any condition, while the 8i-AW feature tighter, deeper grooves to boost spin on approach shots. Laser milling between grooves enhances friction across all lofts, ensuring consistent spin, distance, and launch throughout the set.
