The Mizuno JPX-850 fairway wood utilizes Shock Wave Sole technology to increase distance for improved performance. The sole design allows the club head to flex at impact, transferring more energy to the ball for increased ball speeds. The center of gravity is also moved lower due to the added material in the sole, making it easier for players to get the ball airborne. The Quick Switch hosel allows for a 4º range of loft adjustment in each model to optimize performance for your swing.
