A “Certilogo Code” or “CLG Code” is an identification code used to tag products belonging to those brands who have chosen the Certilogo brand protection solution to fight counterfeits. It is a “human-readable” code composed of 12 digits usually preceded by the acronym “CLG.” Example: CLG 012 345 678 901 or, in some cases, 012 345 678 901. All Nobis’s Jackets have a unique Certilogo protecting your purchase.
