This naturally colored, gunn cut glove constructed from top grain AB-grade cowhide leather, has a keystone thumb which means the glove provides good freedom of movement and is very comfortable to wear. The keystone thumb style is preferred by most safety and health engineers because it is the most ergonomically correct work glove. The gunn cut is recognized by the seam at the base of the two middle fingers. Seamless back, but finger seams are in the back of the fingers for comfort.
