Abstract: Disclosed is a dimple pattern on a golf ball, which consists of a plurality of dimples of various sizes for providing an optimum impact at the moment of hitting the golf ball. The dimple pattern formed on a circumferential surface of a golf ball has a total of 1070 dimples, including first dimples with a diameter of 3.8 mm, second dimples with a diameter of 3.2 mm, third dimples with a diameter of 2.4 mm, and fourth dimples with a diameter of 0.9 mm, wherein the number of the first dimples is 414, and the total number of the second to fourth dimples is 656. As the dimples of various sizes are repeatedly arranged with predetermined spaces, impact pressure is uniformly transferred to the golf ball over an entire contact area with a club face at the moment a golf club impacts on the golf ball, thereby removing the hook and slice, so that the straightness and stability of the golf ball while the golf ball is flying can be improved and the flight distance of the golf ball can be increased.

Abstract: An athletic glove includes a back portion and a palm portion combined therewith to fit the human hand snugly. The respective portions are joined along edges in a substantially continuous manner. The palm portion provides an anti-slip function wherein the back portion includes a composite elastic material, which is a blend of synthetic fiber and spandex. The entire palm portion of the glove includes a single layer of leather having an exterior contact area for gripping.

Abstract: An athletic glove having consistent gripping ability in various moisture conditions includes a palm portion and a back portion joined together to fit the human hand. The palm portion is made of a thin polyurethane-impregnated artificial leather material printed with a pattern of silicone sealant. The pattern is preferably achieved by silk-printing on contact areas of the palm portion with a two-part silicone sealant in repeated patterns of fine lines of a narrow width, to penetrate and bond firmly with the fiber thereof after curing and thereby improve gripping ability over that of bare artificial leather and impart consistent gripping ability in various moisture conditions without losing the original good, soft and supple feel, finger motion, and tactile response of the original material.
