After 4 weeks of discussing cold-resistant specifications, we signed the contract on November 3, 2024. The customer required flame-retardant workwear with -40°C thermal insulation for their mining sites in Siberia. Our design team integrated multi-layered insulation and reinforced knee/elbow patches for durability. The first shipment of 2,000 sets arrived in December, and the mining team confirmed the workwear maintained comfort and protection during extreme winter shifts.
