Why it works

Certified protection that survives industrial laundering

Multi-standard protection

Certified to EN ISO 11612 for heat and flame, EN ISO 11611 for welding and IEC 61482 for arc-flash risk in one trouser.

UV-blocking, ATEX suitable

40+ UPF fabric blocks 98% of UV rays and the trouser is rated for use in ATEX (potentially explosive) atmospheres.

Two-tier knee pad pockets

Two positioning options for knee pad inserts, plus 8 pockets in total including a rule pocket.

Anti-static and limited chemical protection

EN 1149 anti-static fabric is non-magnetic with no ferrous content, and EN 13034 gives limited protection against liquid chemical splash.

Built for repeat industrial laundering

Fabric and sewn-on FR tape hold shape and colour through industrial wash at 75C and tunnel drying at 155C.

Frequently asked questions

What protection standards does the FR66 meet?

The FR66 is certified to EN ISO 11612 for heat and flame, EN ISO 11611 for welding, IEC 61482 for arc-flash risk and EN 1149 for anti-static properties, so one trouser covers heat, flame, welding and arc hazards.

Can I adjust the knee pad position?

Yes. The FR66 has two-tier knee pad pockets, giving you two height positions for the knee pad insert to suit the task.

Is the FR66 suitable for ATEX (explosive atmosphere) work?

Yes, the FR66 is rated suitable for use in ATEX classified areas.

Will the FR66 keep me warm in cold conditions?

The FR66 is not thermal rated, so it has no added insulation layer - it is built for flame, heat and welding protection rather than cold-weather warmth. Layer underneath for cold outdoor work.

Is the FR66 waterproof?

No, the FR66 is not waterproof. It does carry EN 13034 for limited protection against liquid chemical splash, which is a different property to general weatherproofing.

What leg length and sizes are available?

The FR66 comes in waist sizes 30 to 46 in Navy or Orange, with an extendable leg length from 31 to 33 inches.

Can I get the FR66 branded for my company?

Yes, embroidery and logo printing are both available on the FR66. Ask about trade-account pricing for bulk and framework orders.
