TECHNOLOGY 4-PIECE CONSTRUCTION XXIO 13 Irons feature an optimally low Center of Gravity thanks to their 4-piece construction, which includes titanium faces and tungsten-nickel sole weights. That weighting, combined with our unique Rebound Frame structure which alternates stiff and flexible zones for added ball speed, gives you a satisfyingly high launch with incredible distance. TITANIUM FACES The thin, high-strength titanium face, along with hollow portions of the heel, allow for an even larger high-density tungsten-nickel toe weight.
