Prada's most iconic and historically significant handbag is the Prada Classic Black Nylon Backpack, introduced originally by Miuccia Prada in the 1980s, which revolutionized luxury by proving durable industrial nylon could match fine leather. In contemporary collections, the Prada Galleria Bag—crafted from signature cross-grain Saffiano leather with structured lines and a timeless trapezoid silhouette—stands as its most celebrated leather masterpiece.
