Features:

• Engineered with flame retardant yarn specifically for the hot metal industry. The calf length socks are knitted using specialised flame retardant yarns, comprising 70% modacrylic (USA) and 22% fire-resistant rayon (Switzerland) and are reinforced at both the toe and heel.
• Designed with a fine needle count to create density in the knit to prevent molten matter from penetrating the sock or attaching to the surface (compliant with the SABS 1423-1/1987 flame retardancy requirements, category 1).
