The multi-piece golf ball includes a cover, preferably a dual-cover having inner and outer cover layers. The outer cover is preferably made of the EPDM rubber material. The golf ball further includes an inner core, preferably a dual-core containing a center and surrounding outer core layer. The center may be made of a polybutadiene rubber composition and the outer core layer may be made of an EPDM rubber composition. The resulting golf ball has high resiliency, a soft feel, and good weatherability.
