High visibility bodywarmers are garments designed to make workers more visible in low light conditions. They are often worn by people who work in hazardous environments, such as construction sites, airports, and roadwork areas. High visibility bodywarmers come in a range of colors, but the most common are fluorescent yellow, orange, and green. These colors are highly visible and can help to improve the safety of workers who are working in low light or foggy conditions. 

Some high visibility bodywarmers also come with reflective strips, which reflect light from car headlights, making the wearer even more visible. They are typically made from lightweight and breathable materials, which make them comfortable to wear for extended periods of time. High visibility bodywarmers can be worn over other clothing, such as jackets or shirts, to provide an additional layer of visibility. They are available in a range of sizes to fit all body types.
