Frequently asked questions

What does the EN 343 Class 3 rating actually mean?

Class 3 is the top water resistance band under EN 343, tested to withstand 20,000mm of water pressure, so the fabric holds up in sustained rain rather than just showers.

Will I overheat wearing these in warm weather?

The Sealtex Ultra fabric is breathable and windproof rather than fully insulated, so it sheds rain without trapping heat, though it will still feel warmer than going without a rain trouser.

How do the hems fit over boots?

The hems are stud adjustable, so you can tighten them around a boot to keep rain and debris out at the ankle.

Do these have pockets?

No, this is a lightweight over-trouser without pockets, designed to go over your existing workwear in wet weather.

What sizes are available?

Sizes run from S to XXXL, in orange only.

Can I get my company logo added?

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

Are the seams actually sealed, or just stitched?

The seams are welded, not just stitched, which is what stops water getting in at the seam line rather than relying on stitching alone.
