Made from 1.2mm thick Split Cowhide Leather with Flame Retardant cloth back and under arm with shoulder vent for improved comfort. The full leather construction provides maximum protection from radiant heat, spatter, and sparks. The thick cowhide is incredibly durable and resistant to abrasion and punctures. Suited for heavy-duty, high-amperage welding processes like MIG and MMA Stick welding, especially in confined spaces or overhead welding where spatter is a major concern.
