Hi-Viz Safety Waistcoats
High-visibility clothing, sometimes known as "hi-viz", is any clothing worn that has highly reflective properties or a colour that is easily discernible from any background. Most industrial employers require it as a type of personal protective equipment (PPE). Yellow waistcoats worn by emergency services are a common example. Occupational wearers of clothing with high-visibility features include railway and highway workers, airport workers, or other places where workers are near moving vehicles or in dark areas. Some cyclists wear high-visibility clothing when riding amongst motor vehicles. Hunters may be required to wear designated high-visibility clothing to prevent accidental shooting.
