Solid golf ball with thin mantle layer

摘要

A solid multi-layer golf ball includes a core, a mantle layer, and a cover layer. The cover layer and the mantle layer are both made of a thermoplastic polyurethane material. The cover layer is softer than the mantle layer and provided with an optimal thickness for spin and durability. The mantle layer is relatively thin compared to the cover layer and the volume of the ball as a whole. The mantle layer is also harder than the cover layer.
