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. Waffle crown and thick sole weight, developed to provide a low-positioned sweet spot and deep centre of gravity, for a high, stable launch and effective spin count. High-energy face in MAS1C-steel, redesigned with a new variable thickness – made possible by Mizuno’s Cortech Chamber.
