Designed for forgiveness, distance, and feel,the new JPX-800 PRO features the highest COR ever developed in a ledgendary Mizuno one piece Grain Flow Forged Iron. A large cavity is created using a CNC cavity milling process which thins the face to raise ball speeds for maximum distance, and optimizes a low, deep center of gravity or increased forgiveness on less than perfect shots. The JPX-800 PRO delivers a perfectly tuned sound at impact for the ultimate in feel and is extremely pleasing to the eye, with a traditional look at address, minimal progressive off-set, thinner top line an a modest, workable head size. In addition, the sole of the JPX-800 PRO implements an aggressive Tripl Cut design that ensures solid ball striking from all types of lies.
