The Portwest FR416 is a flame resistant hi-vis trouser for work where heat, flame, static and electric arc are all risks. Two-way stretch fabric in the key movement areas lets you kneel, climb and bend freely through the shift.
Storage is well thought out. Zip-off holster pockets keep tools close at hand when you need them, a thigh pocket holds your phone and keys securely, and top-loading knee pad pockets make pads quick to fit. Reinforced, flame resistant panels at the main abrasion points help the trousers last in hard use.
