Cordova Safety Products grades leather according to the area on the hide from which it is cut. The premium-grade leather comes from side or shoulder and from areas higher on the animal that receive the least amount of movement. This glove is constructed of premium grain goatskin. Goatskin is preferred where tactile sensitivity is required. It provides excellent tensile strength and abrasion resistance. The high lanolin content makes it one of the softest leathers available. This goatskin driver offers a Thinsulate® lining, the warmest thin insulation on the market. It features a shirred elastic back and a keystone thumb, which offers the highest range of motion and comfort.
