I am a welder in Salt Lake City, and went so far as to sew my own gloves before figuring out that para-aramid gloves were superior in every way. I had these custom built to be free of all animal products. They are far superior to leather in heat and spark resistance. Made from -para-aramid fibers (we could call it Kevlar if we bought it from Dupont.) and sourced from India, the worlds largest democracy.
