XXIO Men's X Red IronsXXIO (pronounced zeck-see-oh) X Irons combine their most advanced technologies to give you the ideal performance from every club in your set. First, the Hi-Energy Impact Head design expands the COR area of the club face, giving you faster ball speed and greater distance from more impact locations. Titanium club faces in the X irons give you a larger sweet spot as well with faster ball speeds to increase distance. Progressive sole weights made of tungsten nickel are positioned as low as possible in each club to create higher launch and more forgiveness, fine-tuned for each iron. XXIO's lightweight, low swing MOI design gives you more acceleration and speed without having to swing harder. Finally, the light Smart Impact Shaft is engineered to reduce the force on your body during the swing to promote more consistency so you hit the sweet spot more often.
