XXIO (pronounced zeck-see-oh) X Irons combine advanced technologies to give you the ideal performance from every club in the set. A Hi-Energy Impact Head design expands the co-efficient of restitution area of the clubface, giving you faster ball speed and greater distance from more impact locations. Titanium clubfaces in the X irons provide a larger sweet spot as well, and 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.
Lots of forgiveness with plenty of distance with high launch and straight ball flight … The wider sole just glides through the turf and make these easy to hit … Low CG helps for a high launch.
