The number 77 holds a special significance in Chicago Cubs culture and uniform design due to its direct connection to the city's unique geography and municipal identity. When the franchise and Nike introduced their special City Connect uniform series, the design elements were specifically inspired by Chicago's 77 distinct neighborhoods. The apparel, graphics, and promotional campaigns incorporated the number 77 to celebrate the diverse communities spanning across the city that unite under a shared passion for Cubbie culture, emphasizing the team's commitment to being a good neighbor and representing the entire metropolitan area rather than just the North Side.
