The XXIO Prime 10 Irons help golfers experience unprecedented speed and lightweight feel. The Prime 10 Irons feature a thin, lightweight face that is forged from Super-Tix PLUS titanium, in addition to a CNC milled speed groove. This high-strength alloy greatly increases distance performance thanks to a hotter sweet spot that is larger than the preview model. XXIO fits the Prime 10 Irons with their proprietary Prime SP-1000 graphite shaft featuring TORAYCA's T1100G carbon fiber and Nanoalloy resin. The Prime SP-1000 shaft is extremely lightweight with an easy-to-swing profile, which helps you produce more ball speed and distance.
