Hi vis clothing, or high-visibility clothing, is critical safety gear designed to enhance the visibility of individuals in low-light or hazardous environments. This clothing is typically made from bright fluorescent materials, such as neon yellow, orange, or green, and is often equipped with reflective strips that increase visibility by reflecting light. Hi-vis clothing is typically made from bright, fluorescent materials in colors like neon yellow, orange, or green. These colors are highly visible during the day and in environments with good lighting. Additionally, hi-vis garments often feature reflective strips that enhance visibility in low-light conditions by reflecting light from sources like headlights or flashlights.

The primary purpose of hi-vis clothing is to reduce the risk of accidents by ensuring that workers are easily noticeable. This is particularly important in industries such as construction, road maintenance, and emergency services, where workers are often exposed to moving vehicles and heavy machinery.

Standards for hi-vis clothing, such as those set by the American National Standards Institute (ANSI) in the United States, ensure that these garments provide adequate visibility and meet specific safety requirements. Hi-vis clothing is not only about safety but also about ensuring workers can perform their tasks effectively and with peace of mind, knowing they are visible and protected.
