Certified to EN 343 Class 4 for waterproofing and EN 342 for cold protection, rated for wet and cold site conditions.

Heat-applied HiVisTex Pro segmented reflective tape at Class 1 keeps you visible in daylight and low light.

Detachable bib, easy on and off

Frequently asked questions

Is this bib and brace waterproof?

Yes. It's rated EN 343 Class 4 with a water resistance of 30,000mm, taped seams and a PFAS-free Texpel Splash finish that beads water off the surface.

How warm is it for winter work?

It's certified to EN 342 for cold protection and lined with Insulatex Pro insulation, so it's built for very cold conditions without adding excess bulk.

Can I remove the bib section?

Yes. The bib and braces detach from the trousers, so you can wear it as a standard waterproof trouser when the bib isn't needed.

What sizes and colours are available?

Sizes run from S to 4XL, in Orange/Black or Yellow/Black.

Does it have tool storage?

Yes. There are holster-style tool pockets, a zipped thigh pocket, a rule pocket, side pockets, two back patch pockets and a hammer loop.

Can I add my company logo or branding?

No. This style doesn't offer embroidery or logo printing.

Will it fit over a wide work belt?

Yes. The belt loops are wider than standard to take wider work belts.
