All-new All-American RTZ Wedges are made with Z-Alloy, a completely new steel formula that enables a zero-compromise design approach for incredible feel, better durability, and more consistency for our best performing tour Wedges yet. Plus, theres an all-new ADAPT grind featuring full-face grooves (the only full-face option for this generation), to give RTZ Wedges more versatility than ever before. Z-Alloy Z-Alloy is a brand-new steel with better feel. Its softer, lighter, and remarkably durable. It gives RTZ Wedges superior feel, better forgiveness, and more consistency. On RTZ Tour Rack Wedges, Z-Alloys rust-resistant properties ensure longer-lasting, like-new performance. HydraZip HydraZip is a unique system of face blasts and laser-milled lines formulated to maximize spin performance under wet conditions. This technology is dynamically configured by loft groupings, which helps balance spin across lofts, while maximizing spin in adverse conditions ZipCore This low-density core technology replaces heavier material in the heel and hosel area with a lightweight, low-density, vibration-dampening material. This proprietary core allows us to shift the Center of Gravity closer to where you strike the ball, while simultaneously adding MOI UltiZip UltiZips sharper grooves cut through grass and debris at contact, while deeper grooves help make space for grass, sand, dirt, or water to clear the impact zone, giving RTZ Wedges stronger, more consistent spin from the fairway, rough, or bunker.
