Frequently asked questions

Do I wear these over my normal work trousers or instead of them?
Over them. The Iona Lite is designed as a waterproof outer layer, sized generously so it fits comfortably over your existing work trousers.

What waterproof rating do they meet?
EN 343 Class 3, rated to 20,000mm water resistance, plus EN 17353. Taped seams stop water getting in through the stitching.

Do they come in other colours?
Navy is the only colourway currently listed for the S481 Iona Lite.

What sizes are available?
XS through to XXXL, all in the same navy colourway.

Can I get these with a company logo?
Yes, embroidery and logo printing are both available - ask about company branding for team orders.

Do they have any visibility features?
Yes, both legs carry reflective tape at ankle height for added visibility in low light.

How do I get a secure fit around my boots?
The hems are stud-adjustable, so you can cinch them down over boots to stop water running in at the ankle.
