Abrasion resistant goatskin leather and durable keystone 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 blended aramid provides 360° ANSI Level A4 cut protection and ANSI Level 3 puncture resistance. Testing places these gloves at an arc flash level 3 rating, and ANSI level 3 heat rating with protection up to 200°C / 392°F.
