Nike designed the uniforms for this year's World Cup with a dual focus on player performance and national identity, prioritizing comfort in the tournament's challenging heat and humidity. The company collaborated with athletes, coaches, and federations to understand how uniforms impact the game, while also gathering insights from fans about what their team's jersey represents.
Phil McCartney, chief innovation, design and product officer for Nike, stated that this input is merged with scientific innovation to create aesthetically pleasing designs. "We take that and we merge that with all the science and the innovation to make sure that we have beautiful designs," McCartney told The Associated Press.
Other major sportswear brands also contributed to the tournament's kits. Adidas designed jerseys for Argentina, Mexico, and Colombia, while Puma outfitted Portugal, Morocco, and Senegal. Some teams, however, opted for uniforms from different manufacturers.
Nike's design process involved extensive testing in its sports research lab, which features specialized equipment like thermal chambers and motion-capture cameras. This allows for detailed analysis of how apparel performs under various conditions, including heat and humidity. "We take motion-capture to see how they’re moving in the kit, how the kits are responding," McCartney explained. "We also use the thermal chambers that we have to test the kit’s breathability, to test wicking and moisture management."
For the World Cup, Nike developed a new, more breathable fabric made from recycled materials. The jersey construction incorporates mesh stitching in key areas to enhance airflow and improve thermal regulation, a feature players have requested.
Despite rigorous testing, an issue with bulging shoulder seams was observed in some Nike kits earlier in the year, affecting teams such as France and Uruguay. Nike confirmed to the AP that the problem was identified and resolved before the World Cup commenced.
Beyond performance, the visual aspect of the uniforms is crucial for fan connection. McCartney noted that inspiration is drawn from diverse sources, including history, art, music, and culture, to resonate with each nation's identity. For instance, France's away kit is a light green, referencing the Statue of Liberty, a gift from France to the U.S. The kit's interior tag features the word "Liberté" within a silhouette of the statue's crown. The front of the jersey displays a rooster, a national emblem, and two stars commemorating France's past World Cup wins.
France's home kit and Uruguay's kit both feature collars, a design choice influenced by the respective federations. France aimed for a connection to its status as a fashion capital, while Uruguay sought a more classic football aesthetic, harkening back to decades when collars were common in uniforms.
National symbols were also central to the designs for the U.S. and Canada. The U.S. home kit incorporates horizontal red and white stripes, evoking the American flag, while Canada's jersey prominently features a maple leaf. "Especially in an event like the World Cup, we really play into national pride," McCartney said.
