These hi-vis FR holster trousers are built for work where you may face flame, heat, electric arc or static risks. They are also suitable for ATEX environments. Inherent flame resistance is part of the fibre itself, so the protection stays in place through repeated washing.
Two-way stretch fabric and stretch panelling in key movement areas let you kneel, climb and bend freely. Reinforced FR fabric at high-wear points and triple-stitched seams add durability. Ten pockets, including zip-off holsters, give you flexible storage for phone, keys and tools.
