Hi Vis Safety Vests
The class is the compliance point and it is easy to get wrong. A day-use vest relies on fluorescent fabric alone and does nothing once the light goes, while night and day-night classes carry retroreflective tape that returns headlight beams. If any part of the shift runs in low light, specify day-night and be done with it. Sizing over a jacket matters in winter. See protective gear and hard hats.
