An ultra-low compression golf ball is disclosed herein. The core preferably has a PGA compression less than 30. The mantle layer and cover have approximately the same thickness. The cover comprises a thermoplastic polyurethane material and has a specific gravity greater than the core and mantle layer. The golf ball has a PGA compression less than 75 and a COR of at least 0.780.

In a golf ball having a core and a cover of at least one layer encasing the core, at least one layer of the cover is formed of a resin composition which includes (I) a polyurethane or a polyurea, and (II) a core-shell polymer in which the core is a crosslinked acrylic rubber particle and the shell consists of an acrylic polymer, the amount of component (II) included per 100 parts by weight of component (I) is less than 15 parts by weight, and the CS.sub.1 value calculated by formula (1) below

CS.sub.1=(CV.sub.50CV.sub.12)/38(1)

(wherein CV.sub.50 is the coefficient of restitution at an incident velocity of 50.0 m/s and CV.sub.12 is the coefficient of restitution at an incident velocity of 12.0 m/s) is larger than 4.0810.sup.3, thereby to have an excellent controllability, a good feel at impact on approach shots and a good scuff resistance.

Golf balls comprising a multi-layer core and a cover are disclosed. The multi-layer core comprises a center, an intermediate core layer, and an outer core layer. At least one layer of the multi-layer core is a high specific gravity layer.

An ultra-low compression three-piece golf ball is disclosed herein. The core preferably has a PGA compression less than 30. The mantle layer and cover have approximately the same thickness. The cover comprises a thermoplastic polyurethane material and has a specific gravity greater than the core and mantle layer. The golf ball has a PGA compression less than 75 and a COR of at least 0.780.
