How we chose

Our team works with clients every day to test and wear this kit on real sites, and we listen to their feedback alongside what people say online and on review sites. We bring it all together so you get clear, honest information to pick the right product for you.

Using our supplier certification data, we screened the certified picks against EN ISO 24232:2025, which replaced EN 343:2019 on the GB and EU lists in autumn 2026, or EN 343:2019 for stock certified before the change, and read the water penetration and breathability classes (for example 3:1 or 4:1). One pick also carries EN 17353 Type B2 reflective bands. We also read seams, fabric coating and fastenings from supplier specifications.

Every pick is active and in stock, with clear photos and sizes available. Scores weight review quality (38%, a Bayesian average rating), review volume (17%), our product research (30%: trade bestseller signals, price against the market, colour range and verified standards), photo coverage (8%) and size availability (7%). We only show verified ratings and review counts, with links, we pick no more than two products per brand, and every review summary is written in our own words.

Buying guide

Over-trousers

Wide legs and ankle zips let you pull them on over boots.

PU or breathable

PU is very waterproof; breathable fabrics are more comfortable.

Packability

Lightweight suits fold small for a van or bag.

Sizing

Choose a size that fits over your work trousers.

Frequently asked questions

Can I wear waterproof trousers over work trousers?

Yes. Most overtrousers are cut to go over work trousers, and some have side zips or stud hems to help with boots.

Are rain suits breathable?

Breathable membranes reduce condensation for active work. PU and PVC suits are fully waterproof but less breathable, so they suit wet, static tasks.

How do I care for waterproof trousers?

Wash cool and follow the label; reproof when water stops beading.

How quickly will my order arrive?

Plain items usually arrive in 2–4 working days to Great Britain, Northern Ireland and Ireland. Branded items take 7–10 working days. Every order also comes with 28-Day Returns.

Can you add our logo?

Yes. An uploaded logo has a one-off £9.99 setup fee, then £3.99 per position per garment. A text logo has no setup fee and is £3.99 per position per garment.
