The Portwest FR410 Bizflame Rain+ Hi-Vis Multi-Norm Contrast FR Trousers are built for multi-risk environments where several hazards meet. They suit wet outdoor work around flame, heat, electric arc, light chemical splash or explosive atmospheres, all in one garment.
A fully elasticated waist lets you pull them on quickly over your normal clothes. A reflective standards label on the thigh makes the protection levels easy to identify on site.
