The Callaway HEX Chrome golf ball is the best 3-piece urethane ball Callaway has ever made. It's highly durable, has the best HEX Aerodynamics that Callaway has ever developed and features super soft feel that's ideal for players with moderate swing speeds. HEX Chrome is also engineered for high performance from tee-to-green. You can take advantage of high spin around the greens and penetrating distance to play with ultimate confidence on every shot. S-Tech Core features a low compression that produces extremely soft feel off the clubface. Mantle layer is made of an ionomer tri-blend that forms a protective skin around the core and optimizes to keep driver spin low. DuraSpin cover uses a proprietary formulation to significantly improve durability.
