How we picked

  • Every pick is certified to EN 343 Class 4:4, per the manufacturer's data.
  • Plain jackets for trades, plus hi-vis options for roads and sites.
  • X in the rating means the optional rain tower test was not done.
  • Only products in stock on our site when we checked, in October 2026.

We are an independent retailer. These are our picks from what we stock, chosen on the certified markings each product carries. Always check your site rules and the product label before you buy.

What to check before you buy

  • Two numbers: water penetration, then breathability. 4:4 is the top for both.
  • An R means the whole garment was rain-tower tested; X means it was not.
  • Need to be seen? Pick EN ISO 20471 hi-vis, or EN 17353 for medium-risk work.
  • Follow the care label. See our care guide.

Frequently asked questions

What does EN 343 4:4 mean?

Class 4 for water penetration resistance and Class 4 for breathability: the top of both scales.

Is a softshell waterproof?

Softshells are made to resist wind and showers. For heavy rain, choose a jacket rated to EN 343. See softshell vs fleece vs waterproof.

Does a hi-vis rain jacket need two standards?

Yes. EN 343 covers rain protection; EN ISO 20471 covers visibility.
