Professional football jerseys have evolved greatly throughout time, regardless of size. Jerseys were typically composed of thick textiles like wool throughout the 1920s. Teams of the 1930s wore basic colours with distinguishing numbers on their shirts. Teams began to settle on distinctive team colours for their jerseys throughout the next two decades, while colour changes were frequent. The NFL allowed clubs to change uniforms no more than three times during the season in the twenty-first century.
