What Srixon Says:
The XXIO 13 Irons (Graphite Shaft) feature a remarkably low Centre of Gravity thanks to their 4-piece construction, including titanium faces and tungsten-nickel sole weights. That weighting, combined with the Irons unique Rebound Frame structure which alternates stiff and flexible zones for added ball speed, gives you a satisfyingly high launch with incredible distance.

Details & Benefits:

• Rebound Frame – In addition to the L-Shaped Groove at the bottom of the Iron body, new grooves in the outer perimeter of the clubhead improve face COR for added ball
  speed and distance.
• More Forgiving Address – A slightly raised topline with a rounder toe portion looks forgiving at address.
• Tungsten Nickel Weight – The thin, high-strength titanium face, along with hollow portions of the heel, allow for an even larger high-density tungsten-nickel toe weight.
  The toe-side weight optimizes the Center of Gravity location for a higher, straighter launch.
• MainFrame – Variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of XXIO 13 Iron faces that maximizes flex at impact.
