Jean Cassegrain produced the world's first luxury leather-covered pipes, then expanded into small leather goods, such as wallets, passport covers... Longchamp launched its first women handbag in 1971 and became one of France's leading leather goods makers.
The company's real breakthrough came with the use of nylon. In the 1970s, Longchamp created a leather and nylon fabric luggage collection. For the first time, luggage were light, contrary to the overweight suitcases usually sold at that time. This innovation led the company to design a women's handbag known throughout the world: Le Pliage, few decades later.
