The Portwest FR440 Bizflame Work Hi-Vis Contrast FR Holster Trousers are for work where you face several risks at once, including heat, flame and electrical arcs, and need to stay visible. They are suitable for wear in ATEX environments.
Eight pockets keep tools close to hand. The holster pockets zip off and can be moved, so you can set the trousers up for the task or remove the holsters when you don’t need them.
