A compact blade shape, narrow topline, single-piece forging, and narrow sole give ZX7 the workability, feel, and aesthetics of a world-class players iron. Mass repositioned to ZX7's sweet spot and perimeter provide a remarkably soft feel at impact and increased workability. Grooves in the 8i through PW are sharper, narrower, and deeper for more spin and stopping power on approach shots into the green. V-Shaped soles glide smoothly through turf, even if you strike slightly behind the ball. ZX7 Irons also feature the resurgence of our popular sole notches. Tungsten in the toe of ZX7's long and mid irons (3i-7i) increases MOI for more stability while the forged 1020 Carbon Steel body absorbs vibrations for an extremely soft feel. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard Srixon warranty applies and satisfaction is guaranteed.
