A four piece solid golf ball comprises a core 1, an envelope layer 2 encasing the core, an intermediate layer 3 encasing the envelope layer, and a cover 4 which encases the intermediate layer and has formed on a surface thereof a plurality of dimples. The core is formed primarily of a rubber material and has a diameter of at least 31 mm, the envelope layer and the intermediate layer are each formed primarily of the same or different resin materials, and the cover is formed primarily of polyurethane. The intermediate layer and the cover have thicknesses which satisfy the relationship: cover thickness < intermediate layer thickness. The core has a surface hardness (Durometer D hardness) and the envelope layer, intermediate layer and cover have material hardness (Durometer D hardness) which together satisfy the relationship: cover material hardness < intermediate layer material hardness < envelope layer material hardness > core surface hardness. The golf ball provides good controllability, flight, impact feel and scuff resistance. |
