These hi-vis flame resistant trousers are built for demanding work where you need multi-norm protection and visibility together. Two-way stretch panelling in key movement areas gives you a full range of movement when kneeling, climbing or bending, and they are suitable for wear in ATEX environments.
The flame resistance is inherent to the fibres, so it stays effective through washing. FR reinforcement fabric at the main abrasion points and twin-stitched seams help the trousers stand up to hard daily use.
