Reflective vest in the reflective part is using the lattice micro diamond refraction and high refractive index glass beads regression reflection principle, by focusing the post-processing is made of advanced technology. It can direct the light reflected back to shine from afar, no matter in the daytime or night have a good back reflection optical performance. Especially at night, can play as well as in the daytime high visibility. Using the high visibility safety clothing made of reflective material, whether the wearer is in the distant place, or in a light or scattering light interference, can more easily be night drivers found. The emergence of reflective material successfully solved the "see" and "being seen" the overnight traffic problem.
