Reflective vest manufacturers choose reflective materials and brightness when making their products. How should they judge whether it is good or bad?

The brightness of the reflective vest is invisible from the surface. You can use special tools. If you don’t have professional tools, you can use a flashlight to illuminate the reflective cloth. The better the brightness, the brighter the reflective cloth will shine, or The higher the brightness of the reflective cloth illuminated by the car lights at night, the farther the reflection distance will be. The purpose of wearing a reflective vest is to use the high reflective effect of the reflective clothing to improve the safety of the wearer and remind the passing vehicles, so the brightness problem must not be ignored.

We should buy a reflective vest from a regular business. It should be stored in a dry and ventilated room temperature condition to avoid the influence of damaging factors such as extrusion, high temperature and chemical corrosion.
