Abrasion resistant goatskin leather and durable wing thumbs optimize these MIG welding gloves for the long haul, while 6″ gauntlet cuffs provide extra coverage when heat is a hazard. A cut-and-sewn construction gives these gloves a close, dexterous fit, and their lining made with DuPont™ Kevlar® fiber and composite filament fiber provides 360° ANSI Level A4 cut protection and ANSI Level 4 puncture resistance. Testing places these gloves at an arc flash level 4 rating, and ANSI level 2 heat rating with protection up to 140°C / 284°F.
