High visibility clothing classes are defined by EN ISO 20471 and indicate different levels of protection. Class 1 is the minimum level, with at least 0.14m² of fluorescent material and 0.10m² of retroreflective material, suitable for low-risk environments. Class 2 requires 0.50m² of fluorescent material and 0.13m² of retroreflective material, and is recommended for work on urban roads. Class 3, the maximum level, requires at least 0.80m² of fluorescent material and 0.20m² of retroreflective material, ideal for work on motorways or high-risk environments. At RAG Tailors, our high visibility trousers are classified according to these standards, ensuring that each professional has access to the level of protection appropriate to the specific requirements of their role.
