Frequently asked questions

What does "Multi-Norm FR" mean for this trouser?

It means the FR426 is certified to multiple EN and IEC standards in one garment, including flame resistance (EN ISO 11611), arc flash (IEC 61482), antistatic (EN 1149) and cold protection (EN 342), rather than a single-standard FR trouser.

How waterproof is it?

The FR426 is rated to EN 343 Class 4, the highest waterproofing class in that standard, with 30,000mm of water resistance.

Is it warm enough for winter outdoor work?

Yes. It carries a high insulation thermal rating and is fully lined and padded, suited to very cold conditions.

Can I wear it over other trousers?

The bib-and-brace design with detachable braces and elastic waist is built to layer over base trousers or thermal layers; check your usual size for fit over layers.

What is the difference between the two colourways?

Orange/Black and Yellow/Black are both EN ISO 20471 Class 2 hi-vis; the choice is down to site colour policy or personal preference.

Can I add my company logo?

Yes, embroidery and logo printing are both available on this trouser - ask your account contact for details.

Is it suitable for welding or arc-flash environments?

The fabric is certified to EN ISO 11611 (welding) and IEC 61482 (arc flash), so it is suited to sites with that risk, alongside its FR and hi-vis properties.
