The Flame Retardant Edge Harness is designed particularly with welding or other high-heat applications in mind. Its revolutionary design allows the user to easily replace its outer, fire retardant shell, thereby contributing to a vastly increased product lifetime. Simply unbutton the old shell, re-button the new shell, and you are ready to go back to work. Features Di-electric dorsal D-ring, and 5 points of adjustment for easy adjustability.  Manufactured by Guardian.
