Warrior's new Deep Cavity - Wide Sole Technology is what does it. First, we expanded the sweet spot by moving some of the mass out from behind the center of the club to balanced spots around the perimeter. So while the sweet spot in most clubs is somewhere in the center of the club face, Warrior's new Irons feel just as solid no matter where you hit the ball. They're all sweet spot! Second, we moved weight back, away from the face, producing a very low center of gravity allowing the ball to get up and out for longer, straighter shots with more control on impact. Combined this means greater distance and more accuracy no matter where you hit the ball, shot after shot. They're the most forgiving clubs you'll ever hit!
