This is a fluorescent yellow reflective vest. Its main material is mesh fabric, which has good air permeability and is relatively comfortable to wear. There are two conspicuous silver-gray reflective strips on the vest, located on the front chest and back respectively. Under the illumination of light, they can strongly reflect light, thereby improving the visibility of the wearer and ensuring safety. The vest is designed with a zipper for easy putting on and taking off. And there is a pocket on the chest that can be used to place some small items. This kind of reflective vest is usually suitable for work scenarios that require high visibility, such as construction sites, road construction, and traffic control. It can effectively remind people around to pay attention and avoid accidents.
