The Yonex EZONE SD irons combine a variety of advancements designed to provide superior distance. A thin clubface is combined with a double undercut cavity to increase the area of maximum power, whilst a shock-absorbing sheet of graphite behind the face is designed to maximise feel. The Combination Power Weight System progressively adjusts the position of the weight on the clubheads throughout the set to suit the needs of each individual iron. Mixed with new Sole Design that minimises drag, the Yonex EZONE SD irons provide a clean, powerful ball stike.

The EZONE SD irons come complete with either a Nanospeed 200 graphite shaft or a lightweight NS950 steel shaft.
