Why it works
Engineered for hazardous environments
Certified heat and arc protection
Meets EN ISO 11612 for heat, EN ISO 11611 for welding and IEC 61482 for arc flash risk.
Built for kneeling and bending
Two-tier knee pad pockets and a stretch crotch gusset reduce fabric stress in awkward working positions.
Reflective leg bands
Reflective tape bands on both legs improve visibility, in Navy or Orange colourways.
UV and static protection
40+ UPF fabric blocks 98% of UV rays, with EN 1149 antistatic performance for static-sensitive environments.
Non-magnetic build
No nickel or ferrous fixings, so the trousers will not interfere with sensitive equipment or magnetic environments.
