The main body of the reflective vest is mainly made of mesh cloth or some plain weave cloth. The reflective material is generally made of reflective lattice, and some are made of high-brightness reflective cloth. The important part of the reflective vest is reflection. This part adopts the principle of lattice reflection, which is mainly made by a series of advanced processes after focusing. It can instantly reflect the light coming from a distance back to the luminous place, whether it is day or night, it can have a good retroreflective optical effect.
