What is High Vis Clothing?
What is high vis clothing should be an easy answer question, but it is far from it. High-vis clothing can come in various colours and materials. It can become quite confusing to clearly see what is a high vis and what isn’t, especially under the different & strict high vis laws of each country.
Fluorescent high-vis clothing is made with special pigments which reflects the invisible ultraviolet light as a bright visible light. These bright colours must provide strong contrast against many backgrounds (man made & natural) to increase visibility.
