Abstract
Abstract A golf club grip has a double-layer structure comprising an inner layer and an outer layer aminated on the outer surface of the inner layer. One of the inner and outer layers is made of a first material, while the other layer is made of a second material. The first material has an elasticity which is higher than that of the second material so that the first material is more readily elastically deformable than the second material, while the second material has a viscoelasticity which is higher than that of the first material.
