In a rapidly changing quarter of the Prada world, the nylon bag may not be the most prominent of that, but it can be said that it is Prada family's most hard-working one. In the 1970s, the Prada family business was on the verge of bankruptcy. Miuccia Prada and her husband, Patrizio Berthelli, were in jeopardy and took over the family business. Miuccia has a keen sense of fashion and bold innovation, her first priority is to Prada products materials and design for some reform. At the beginning of the 20th century, most of the people who bought Prada were nobility and merchants. They often tired of large and bulky leather goods, people are looking for a wear-resistant, waterproof and lightweight products. By chance, Miuccia discovered a military parachute material at the Air Force Base, which is lightweight, wearable and waterproof, and is not afraid of open flames. Then, Prada's first black nylon backpack Vela first appeared in the 1984 autumn and winter series, with great success. After the nylon bag surrounded by all kinds of new elements more and more highlights the young glory, just the old Prada darling SashaPivovarova has been in a row in the ad and nylon bag intimate contact. 2009 autumn and winter, Prada nylon family once again to its civilian price, the classic make a comeback.
