Both hi-vis colours are compliant with EN ISO 20471, so the better option depends on your working environment:
SMI stocks both hi-vis yellow hoodies and orange hi-vis jumpers, so you can choose the right gear for your job role, without compromising on comfort or compliance.
Orange hi-vis, such as an orange hi-vis zip-up hoodie or fleece pullover, is typically required in sectors like rail and highways. That’s because orange stands out more clearly than yellow in certain outdoor environments, making it safer.
TOP TIP: Always check what colour is specified in your industry’s safety guidelines.
Fleeces are typically warmer than sweatshirts, offering better insulation in cold conditions.
If your team is working outdoors or in low temperatures, a fleece - especially a hooded or full-zip style - is often the better choice.
That said, hi-vis sweatshirts are a versatile layer. They can be worn comfortably under jackets or paired with waterproof shells for extra protection.
You can shop the full collection of hi-vis sweatshirts and fleeces directly at SMI.

All are sourced from trusted brands and meet strict workwear safety standards.
The key safety benchmark is EN ISO 20471. It defines the visibility and reflectivity levels required for hi-vis garments used in professional environments.
To comply, garments must feature fluorescent fabric and a set pattern of reflective tape.
These are placed in specific areas to maximise visibility. All hi-vis sweatshirts and fleeces available from SMI meet this standard.
