HydraZip Our proprietary dynamic blast and laser-milled line system creates roughness to enhance friction on the face—maximizing spin in wet or dry conditions, and from anywhere around the green—while also reducing glare at address. ZipCore Set in the heart of CBX 4 ZipCore Wedges, this lightweight and low-density core technology works in concert with the cavity back design—reducing vibrations while also shifting weight and boosting MOI for increased feel, control, consistency, and forgiveness over last generation. UltiZip UltiZip’s network of sharp, deep, and tightly spaced face grooves maximizes performance at contact. By slicing through and channeling debris to bite harder, UltiZip offers purer spin, more control, and more consistency. Dynamic Sole Grinds CBX 4 ZipCore Wedges come automatically paired with a dynamic V-, S-, or C-Shaped sole, depending on the Wedge’s loft, each selected by our engineering team to help improve your greenside shotmaking ability.
