Balenciaga has been cranking out street style hits (the striped market tote, the spandex over the knee boots, etc) for several seasons now, and the Spring '18 shows made it clear that the French brand's new must-have is a triangular duffel bag―seen in a variety of sizes and colors from New York to Paris, and everywhere in between.
