Nike, Adidas, and Puma unveil World Cup uniforms amid heat challenges

Nike has designed uniforms for national teams including France, Brazil, the U.S., and Canada, prioritizing breathability and comfort for players during the World Cup, which faces high temperatures. Adidas and Puma also introduced cooling gear for teams such as defending champion Argentina and host nation Mexico. Nike's Phil McCartney emphasized collaboration with athletes and fans in the design process to reflect national pride, incorporating symbols like the rooster on France's jersey and a maple leaf on Canada's. Despite initial issues with jersey seams, Nike claims to have addressed these concerns before the tournament. Testing at Nike’s facility included thermal chambers to assess fabric performance under heat and moisture.
