Hi-Vis or hi viz reflective sweatshirts – also known as High Visibility Safety Sweatshirts – are used around the United States and around the world as a safety and precautionary measure by employees in work environments which need to be seen to prevent potential injuries. High Visibility Safety Sweatshirts are used on construction sites, by heavy equipment operators, truck drivers, first responders, motorists, runners, walkers, and more in high traffic areas to increase visibility and reduce potential injury. Designed to increase visibility in low-visibility or crowded locations, hi-vis reflective sweatshirts can have logos or other text added to provide enhanced identification of essential personnel. Hi-Viz reflective safety sweatshirts are available in a variety of weights as well as pullover (hoodies) or zip-up styles.
