Combined certification - Class 3 system
If a garment doesn´t reach EN ISO 20471 class 3, it can be combined with other High Visibility garments to reach the highest class of certification - a Class 3 system. For example, a jacket that only reaches class 2 can be worn together with a class 1 or class 2 trousers / bib & brace to reach a Class 3 system. If a garment is certified as a Class 3 system, it is indicated in the product description of the garment.
