Prada was founded by Mario Prada in 1913. Initially, the shop sold leather goods and imported English steamer trunks and handbags. Gradually throughout the 20th century, Prada ascended into a high-fashion brand with hit lines such as the classic Prada handbags and nylon tote. Prada Sport is quite simply the leisure line from Prada. Prada Sport eyeglass frames are designed to be more robust and practical than those by Prada; durable frames are designed for comfort and an active lifestyle, as well as maintaining its high end, fashionable reputation. Prada Sport is often referred to as "linea rossa", meaning red line, as this is a detail that features on all of their Prada Sport sunglasses and is synonymous with the Prada Sport collection.
