The parka features a wind-blocking interior snow belt, full-elastic back with quad-stitching, and durable YKK® #10 brass two-way zipper on Nomex® tape for secure operation in low-temperature conditions. Thermally applied FR reflective trim provides 360° visibility, making the parka suitable for workers exposed to winter hazards, low-light conditions, and arc flash risks requiring NFPA 2112 and NFPA 70E compliance.
