ST-Z 230

Mizuno’s Cortech Chamber encapsulates a stainless steel weight in TPU elastomer, which reduces tension in the face and creates an additional energy source. At the same time, it moves weight closer to the face to reduce spin and contribute to a more solid, powerful feel at impact. Crown in carbon composite, for a low centre of gravity and better stability on off-centre hits. More weight moved towards the back of the head, an additional 8 grammes of rear weight balances the heavier front for consistent ball flight. High-energy face in MAS1C-steel, which is reworked with a new variable thickness design to promote high ball speed.
