The Srixon ZXi5 Irons features a slightly wider sole with moderate blade length and offset, giving attuned golfers enhanced distance, forgiveness, and workability all with an ultra-clean look at address. ZXi5 Irons represent Srixon's most potent blend of power, playability, and ultra-sharp looks. Their revolutionary i-FORGED process, combined with the latest Srixon ball speed and distance technologies, gives ZXi5 Irons unprecedented feel, speed, and power on every shot. 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 ZXi5 are softened to improve this already exceptional feel. MainFrame saves additional weight and adds more MOI through an enhanced network of milled channels on the back side of the Iron face. At impact, this system amplifies ball speed and adds forgiveness. Srixon's Tour V.T. Sole's proprietary combination of sole widths, bounce angles, and notches to ensure a smooth glide through fairway, rough, and sand without any loss of speed. The 3i-7i feature wider grooves, while the 8i-AW have deeper, closer-set grooves to ensure consistent spin across the set. Laser milling between each groove, on every loft, enhances adds bite on every strike. Fitted as standard with the Dynamic Gold Mid shaft and Golf Pride Tour Velvet 360 grip.
