Soon, he heard that the cotton trousers worn by the gold digger were easily worn out, and everyone complained bitterly. Strauss had a brainwave. He cut out a New Pants with a low waist, straight legs and a narrow hip circumference from the thick canvas he carried with him, which was very popular with gold miners. Because these pants are durable, they look smart and agile, and they are deeply loved by cowboys. They quickly became popular among them, and have since become the characteristic clothing of cowboys. Levi Strauss also made a fortune, applied for a patent at 187 1 and established Levi Strauss Company, which has now become an international company with a sales network all over the world.
