Wilson Staff Di9 Iron Set

Features and benefits of the Wilson Staff Di9 Irons:

More distance achieved through a low profile and wide sole that lower the centre of gravity in the clubhead and produce a higher and straighter ball flight with greater power.
A hot, responsive face that generates ball speeds that are superior to comparative clubs from the other leading manufacturers.
Additional of a toe-friendly cavity in the clubhead that extends the sweetspot towards the area where the majority of shots are hit.
The wide sole also moves the centre of gravity deeper in the clubhead for greater stability on your off-centre hits.
