Fairway woods Mizuno ST-Z 230 A high launching, adjustable fairway wood with low to medium spin. Although it was developed hand in hand with our tour consultants, the medium sized wood is playable for all skill levels. The use of a high-energy MAS1C steel face, reinforced with Mizuno's CORTECH chambers, provides exceptional ball speeds and a powerful, solid feel. CORTECH-Chamber Mizuno's CORTECH-Chamber surrounds a stainless steel weight with elastomeric TPU - this relieves the impact surface and creates an additional source of energy. At the same time, the weight is positioned closer to the clubface to reduce spin rate and contribute to a more solid, powerful feel at impact. Extended front-to-back weight distribution Additional 8 gram backweight balance with heavier front section for consistent launch characteristics. Quick Switch Hosel Adjustable up to 4 degrees. Carbon composite crown For a low centre of gravity and stability on off-centre shots. High-energy MAS1C face With new multi-thickness design - made possible by the Mizuno CORTECH-Chamber face reinforcement.
