Hi-Vis Shorts for Site Work & Outdoor Jobs UK

Frequently asked questions

• Do I need hi vis trousers to achieve Class 3 compliance?

  Yes. EN ISO 20471 Class 3 requires a total area of fluorescent material and retroreflective tape that a jacket or hoodie alone cannot meet. Pairing a certified Class 2 hi vis upper garment with certified hi vis trousers gives you the combined coverage required for Class 3. This is the standard approach on roadside, rail-adjacent, and high-traffic construction sites across the UK.

• What is the difference between hi vis trousers and hi vis tracksuit bottoms?

  In our range they are the same garment — fleece jogger-style bottoms with retroreflective tape and fluorescent panels, certified to EN ISO 20471. They are sold individually and as part of complete tracksuit sets. If you already have a certified hi vis top, buy the bottoms separately to complete your Class 3 kit.

• Are your hi vis trousers suitable for roadside work?

  Yes. Our hi vis trousers are available in orange/navy and orange/black — standard for roadside, highways maintenance, and traffic management environments. Worn with a certified EN ISO 20471 orange hi vis upper garment, they provide the full-body visibility required for Class 3 compliance on UK roads.

• What sizes do your hi vis trousers come in?

  Our hi vis trousers are available in sizes Small through to 3XL across most colourways. The elasticated drawstring waist accommodates a range of waist sizes within each size band. Check the individual product listing for size availability in your preferred colourway.

• Can I buy hi vis trousers without a matching top?

  Yes. All hi vis trousers in this collection are sold as individual bottoms — no need to buy a full tracksuit set. If you already have a certified hi vis hoodie, polo shirt, or jacket, add the trousers to complete your EN ISO 20471 Class 3 kit.

• How do I care for hi vis trousers to maintain their certification?

  Machine wash at 40°C. Do not use bleach or fabric softener. Do not tumble dry — hang to dry away from direct sunlight to preserve the fluorescent fabric and reflective tape. If the fluorescent colour has visibly faded or the tape is peeling, the garment may no longer meet EN ISO 20471 and should be replaced.
