Frequently asked questions

Is this trouser a standalone item or worn over other clothing?

It's an over-trouser, cut to slip on over your normal work trousers rather than replace them, with a fully elasticated waist for a quick fit.

How waterproof is the F441 in practice?

It's rated EN 343 Class 3, the highest waterproofing class in that standard, at 20,000mm water resistance, with taped seams so water doesn't get in through the stitching.

What colours and sizes are available?

Navy runs from XXS to 6XL. Black is more limited, available in S, M, XXXL and 6XL - check the size chart for your size in each colour before ordering.

Does it have any visibility features?

Yes, it meets EN 17353 Type B2 for enhanced visibility and carries reflective tape at both ankles for low-light conditions.

Will these keep me warm in cold weather?

No, they carry no thermal rating - they're built to keep rain out, not add warmth, so wear them over insulated layers when it's cold.

Can I get these branded for my team?

Yes, embroidery and logo printing are both available - ask about company branding for team orders.

How do I stop water getting in at the ankle?

The hems are stud-adjustable, so you can cinch them down snugly over your boots.
