Backpack with drawstring and thin shoulder straps of the new Revival 2.0 line, a re-edition of a historic line, as part of the Ecoduck sustainability project, with which Mandarina Duck contributes to the protection of the environment, was produced using a fabric obtained from recycled plastic bottles (PET) that has a distinctive texture reminiscent of packaging plastic and is enriched with a lining, also recycled, in contrasting color. All models are presented in a transparent pocket in which they are folded and inserted. The pocket is part of the product itself and in some of the models it becomes a real additional pocket.
