Reflective vest in the reflective part of the use of the lattice of the micro-rhombus type refraction and high refractive index of glass beads back to the principle of reflection, through the post-processing of advanced processing technology made. It can reflect the distant light back to the light, both in the day or night have a good retroreflective optical performance. Especially at night, can play the same as the day of high visibility. The use of this high-energy reflective material made of safety clothing, whether the wearer is in the distance, or in the light or scattered light interference, can be relatively easy to be found by the night driver. The appearance of reflective material successfully solved the "see" and "seen" this night driving problem.
