Mechanix developed the Regulator for MIG welders working in heavy construction where sharp materials are at work. Regulator welding gloves are crafted with Durahide Boar leather, constructed with DuPont™ Kevlar thread, and lined with ANSI A4 cut-resistant fabric to protect working hands under the hood. Our HiRoller™ fingertip design repositions exposed seams to improve dexterity, durability and control. Featuring reinforced fingertips provide crucial heat resistance and increased wear, FR cotton lining provides added thermal protection and glide-resistant leather side seam reinforcement protects from surface burns while you work.,Size S
