The advanced Progressive Spin Technology means wider grooves in the lower lofted wedges for optimal launch and control, while the higher lofted wedges have narrower and denser grooves to ensure a smooth trajectory through all lofts. The Versatile Grind with rounded front edge and heel and toe grind offers more shot options and adapts to medium to firm surfaces. Supplied with a 120-gram steel shaft with wedge-flex, providing stability and control in every shot. Whether you need maximum spin around the greens or precise approach shots, Cobra Pur is an obvious choice for the discerning golfer.
