Wilson Zip Golf Balls

Features Behind the zero-compression core is a high-velocity Neodymium catalyzed polybutadiene. The unique rubber blend in the core uses a minimum of curatives to produce an ultra-soft (very low compression) core with good resilience Patented HPF mantle layer encases the zero-compression core with a speed-generating mantle for distance and higher iron spin rates Super-soft ionomer cover grabs the club face for higher spin and amazingly soft feel Unique flat-bottomed, shallow dimples rip through the air to create a more stable, penetrating flight
