A golf ball comprises (a) a core, (b) an inner mantle layer, (c) an intermediate mantle layer, (d) an outer mantle layer and (e) at least one cover layer, and the material flexural modulus (FM) of the core and the various layers follows the relationship FM(core)<FM(inner mantle)>FM(intermediate)<FM(outer mantle)>FM(cover), or the relationship FM(core)<FM(inner mantle)<FM(intermediate)>FM(outer mantle)>FM(cover). |
