The new Wilson D7 Golf Irons offer great value for your money. Featuring 'progressive power holes' they provide maximum distance & optimised weighting for a more consistent performance. Wilson say the "D" in D7 stands for distance! Incorporating Wilson's RE-AKT Technology giving the golfer power where it's needed. In the longer irons (4-7) there are three rows of power holes, ensuring maximum distance, & in the shorted irons there are fewer power holes for maximum feel & distance control.
