This Syzmik Pant provides inherent protection from fire and arc flash. It is made from a highly breathable and soft Modatech® fabric that consists of 60% modacrylic, 35% cotton, and 5% elastane, which are all flame resistant materials that meet the standards of NENS, ISO, and NFPA. The pant also has a hoop tape configuration on the legs that enhances visibility and a FR rated heat transfer label that shows the FR rating of HRC 1, which means it can withstand exposure to an arc flash of up to 4 cal/cm2. This product is suitable for workers who need to stay comfortable and protected in environments where fire and electrical hazards are present.
