Bridgestone's J15 wedges are designed to boost spin and versatility through their Sure Contact Sole, Pro Groove Design, and Durable Heat Treatment.
Bridgestone engineers increased consistency by eliminating the hand grind process and building heel/toe relief into the forging process.
This is the major innovation behind the Sure Contact Sole.
Available lofts: 50°, 52°, 54°, 56°, 58°, and 60°.
Besides Bridgestone's Sure Contact Sole, Bridgestone engineers use their Pro Groove Design. The Pro Groove Design increases the inner groove area to help channel dirt, water and other debris away from the face to increase spin.
Bridgestone's Durable Heat Treatment is a heat-treatment applied to the face. This reinforces the face to boost feel and performance.
