Why it works

Built for cold, wet site work

Class 2 visibility

Heat-applied segmented reflective tape meets EN ISO 20471 Class 2 for visibility in low light.

Waterproof to Class 3

Taped seams and an EN 343 Class 3 waterproof rating (20,000mm) keep water out in heavy rain.

PFAS-free finish

The Texpel Splash Eco water-repellent finish is PFAS-free, beading water away without banned chemicals.

Converts to a trouser

Zip the bib and braces off completely to turn the garment into a standard trouser.

Reinforced for durability

Reinforced panels in high-wear areas and twin-stitched seams throughout stand up to daily site use.

Frequently asked questions

Can I remove the bib to wear it as a standard trouser?

Yes. The bib and braces zip off completely, so you can use the PW351 as a full bib-and-brace trouser or as a standard waist trouser depending on the conditions.

How warm is the lining?

The inner Insulatex lining is rated for very cold conditions, so it is built for winter site work rather than mild weather.

Is it actually waterproof, not just water resistant?

Yes. It carries an EN 343 Class 3 rating (20,000mm) with taped seams, and the Texpel Splash Eco finish beads water off the fabric surface.

What is the difference between the Orange/Black and Yellow/Black options?

Both meet EN ISO 20471 Class 2 and share the same features. Orange/Black runs S to 4XL, and Yellow/Black runs S to 5XL.

Can we add embroidery or a printed logo?

Yes, embroidery and logo printing are both available to order. Ask about trade-account pricing for bulk runs.

Will the reflective tape and waterproofing hold up over time?

The reflective tape is heat-applied rather than sewn on, and the seams are taped and twin-stitched, so both are built to withstand regular wear and washing rather than a single season.

Is there storage for tools, not just pockets for hands?

Yes. It has zip-off holster pockets, cargo pockets, a rule pocket and a large back zip pocket, so there is dedicated space for tools as well as general storage.
