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. Select-grade leather is selected from the areas of the hide that don€™t quite make the Premium grade, but are still a higher-quality leather. The regular and economy cuts are selected from the middle and lower portions of the hide, making it thinner than other grades. This glove is constructed of a select grain cowhide palm and brown split cowhide back. It is Kevlar® sewn for added strength and durability. It is also unlined and features a shirred elastic wrist, and a keystone thumb for the highest range of motion and comfort.
