Reflective vest is made of high-strength reflective material, which can make traffic police, police, drivers and passengers on duty or deal with emergency accidents smoothly at night or in special weather conditions, so as to reduce unnecessary casualties. It plays a special role in human production and life, especially in traffic engineering. This kind of reflective vest is widely used in the fields of safety, safety protection for drivers, construction machinery, traffic safety, etc.

The reflective part of the reflective vest is made by using the principle of lattice microrhombic refraction and high refractive index glass beads regression reflection, through the advanced technology of focusing and post-processing. It can reflect the distant direct light back to the light source, and has good retroreflective optical performance in the day and night. Especially at night, it can play the same high visibility as during the day. The safety clothing made of this high visibility reflective material can be easily detected by night drivers whether the wearer is far away or under the interference of light or scattered light. The emergence of reflective materials successfully solved the problem of "seeing" and "being seen" at night.
