Speed Groove
XXIO X Irons feature a milled speed groove on the backside of their faceplate. This channel around the perimeter flexes at impact, rebounding added energy back into the ball for incredible distance.
Weight Plus
Brass and rubber weights in the butt-end of each club raise balance points to unprecedented heights. The effect is a smooth and easy swing that also helps you consistently find the ideal top-of-swing position for more power.
