91635 MESH REFLECTIVE Rucksack in Mesh Reflective. This fabric, here double-layered on the outside with a nylon mesh that creates a three-dimensional effect, is highly reflective owing to a coating made up of thousands of glass micro spheres. It reflects and intensifies the brightness of the colour of the fabric itself, particularly if placed in the dark. The coating makes the fabric water and wind resistant. Front pocket with zip-fastening hidden by a snap fastening flap.
