 Reflective material is created with tiny spherical glass beads (1/2 the size of a human hair).
 Made from optical-grade glass, these perfect microscopic spheres are coated on one side with aluminium and then organized aluminium-side down and adhered to material to create a reflective surface.
 The process allows light to bounce directly back to its source.
 No matter what angle the light strikes the material, the wearer is illuminated and seen.
