1831 Green Spark Guard Flame Resistant Standard Weight Pants are excellent for use in welding, maintenance, metal fabrication and the steel industry. Spark Guard gives a permanent flame resistant finish even after 50 washings. Pants are fully cut and made with cotton so they're lightweight and comfortable, as well as anti-static and rot and mildew resistant. Material is a cost-effective alternative to leather and other heavier welder's clothing materials. Pants have belt loops, a zipper with leather reinforced front snap, two side and two rear patch pockets, and meet ASTM D6413-99 safety standard.
