These Portwest FR450 PW3 Modaflame Work Hi-Vis Multi-Norm Class 1 FR Trousers are for work where several hazards are present at once and you need to stay visible. One garment covers multiple protection needs, so you can wear one pair across a range of tasks.
The flame resistance is built into the fibre and stays through washing. Reinforced panels, triple stitching and stretch panelling make them hard-wearing and easy to move in, while eight pockets keep your phone, keys and tools close to hand.
Key features
