A golf ball (10) is described having a core (26) with a multi-layer cover with a thickness of at least 3.6 mm (0.142 inches) and a Shore D hardness of at least 60. The combination of a core (26), preferably soft core, with a thick, relatively hard multi-layer cover results in a ball having better distance than conventional golf balls having a comparable coefficient of restitution.

La combinaison d'un noyau (26), de préférence un noyau mou, avec une enveloppe multicouche épaisse relativement dure donne une balle de golf ayant une meilleure distance par rapport aux balles classiques à coefficient de restitution comparable.
