Golf ball with multi-layer cover

A golf ball, comprising:

• a core comprising a metallocene catalyzed polyolefin, the core having a coefficient of restitution of at least about 0.650 and a PGA compression of no greater than about 85;
• and
• a multi-layer cover disposed about the core, at least one cover layer comprising an ionomer, the cover having a thickness of at least about 3.8 mm (0.150 inches) and a Shore D hardness of at least about 60, the ball having a coefficient of restitution of at least about 0.770.

A golf ball comprising:

• a solid core having a PGA compression of no greater than about 85, and
• one or more cover layers disposed about the core, the cover layers having an overall cover thickness of at least about 3.6 mm (0.142 inches) and a Shore D hardness of at least about 60, wherein at least one cover layer comprises a high acid ionomer resin having at least 16% by weight of an alpha, beta-unsaturated carboxylic acid.
