Portwest FR434 Bizflame Rain+ Hi-Vis Multi-Norm Contrast FR Winter Trousers – Product Description

The Portwest FR434 Bizflame Rain+ Hi-Vis Multi-Norm Contrast FR Winter Trousers provide high level protection in demanding multi-risk environments. Designed for cold, wet and hazardous conditions, these insulated hi vis trousers combine flame resistance, arc flash protection, chemical splash resistance and waterproof performance in one durable garment.

Made with Bizflame Rain+ HV fabric, they feature a flame resistant waterproof outer that prevents water penetration while maintaining protection against radiant, convective and contact heat. The trousers are fully lined and padded to retain warmth, with an FR cotton lining for added comfort during long shifts in low temperatures.

The fully elasticated waistband allows the trousers to be pulled on easily over other clothing, and the side zip leg openings provide quick access when wearing work boots. Sewn on flame resistant reflective tape ensures lasting visibility, and the reflective standards label on the thigh makes compliance easy to verify on site.

Anti static properties and suitability for ATEX environments make these winter trousers ideal for petrochemical, utilities, rail, engineering and energy sectors. When paired with the FR617 Winter Jacket, they offer full head to toe multi norm protection.
