F-MAX IRONSA lighter overall club weight generates more club speed and distance for golfers with moderate swing speeds. A 5 gram lighter shaft allows you to swing faster around your body using the same smooth tempo. A low profile, cavity back design with greater lofts will help golfers launch it higher and longer, effortlessly. Heel-biased weighting keeps shots in control and straight down the target line more consistently for more GIR's & birdie opportunities. Progressive hosel lengths and progressive offset through the set improve launch and accuracy in the long irons, mid irons and wedges.
