Coretech technology, The durable face can be made thinner than before. Using the Coretech technology, Mizuno’s engineers have created variable thicknesses on the face to increase COR across larger areas than on previous models. This lets you achieve higher ball speed
Wave technology, By creating a wave-shaped cavity between the face and sole, the face gets extra flex on low connections. This gives you increased ball speed with your fairway clubs on shots outside the sweet spot.
