How Nike Makes its Football World Cup Shirts Sustainable

For elite athletes, every tiny detail counts. A millimetre could mean joy or heartbreak: data is the difference between victory and defeat.

This truth is compelling when it comes to competition and training kit. Which is why Nike has combined cutting-edge manufacturing with daring design to produce kits for the FIFA World Cup 2026 that are “light, unrestrictive and comfortable” – and setting new sustainability standards.

Janett Nichol, VP, Apparel & Advanced Digital Creation Studio Innovation, Nike, says: “Nike exists to make athletes better and our breakthrough Aero-FIT technology delivers the future of our industry-defining apparel innovation in both elite performance and sustainability at scale.”

Merging innovation and tradition

The World Cup, which begins in June and runs for a month, is being played across the US, Canada and Mexico. Hot and humid weather is expected to play a big part in the tournament, which makes light and cool kits essential.

Nike says it is “setting a new standard for national team kit design: merging pinnacle cooling innovation with time-honoured tradition and bold visions for the future”.

It says its 2026 Federation Collections also offer a “deep exploration of each federation's heritage, culture and identity”.

It adds “Home kits are anchored in each federation's DNA, while away kits are designed as future classics, creating bold and authentic expressions for a new generation.”

Janett adds: “We’re incredibly proud that our jerseys worn next summer will feel light, unrestrictive and comfortable for an entire match.

“That’s the kind of comfort that helps an athlete stay completely focused on the competition for 90-plus minutes.”

Removing climate as a variable

Nike President Amy Montagne says: "Our national team kits start with the athletes who wear them and the fans who stand behind them.

"These players carry a nation on their backs and their kits travel with football culture far beyond the pitch.

“We take that pride seriously. These kits bring the best of Nike together with an apparel innovation designed to remove climate as a variable for athletes and design that reflects a deep connection to each federation's DNA – creating something athletes feel proud to wear and fans feel truly connected to".

Nike's Aero-FIT performance cooling technology is central to this vision. It uses computational design and a specialised, stitch-specific knitting process to help athletes stay cool in the extreme conditions expected throughout this summer's tournament.

How does Aero-FIT work?

Nike says that Aero-FIT is its “pinnacle expression of cooling technology, capable of channelling more than double the airflow of legacy Nike athletic apparel to help enable peak performance in extreme conditions”.

It adds that it is designed to move more air between skin and fabric, supports sweating efficiency and helps athletes stay dry.

It is Nike’s first elite performance apparel made from 100% textile waste, which helps the brand’s decades-long commitment to reduce its carbon footprint and help athletes adapt to the impact of climate change.

The new cooling technology will debut at the World Cup before extending across Nike’s products.

Other features include:

• Elliptical mesh zones with a unique visual signature
• Lighter mesh that provides greater airflow in high-heat areas.

Producing the apparel with 100% recycled textile is made possible through advanced chemical recycling, a circular process that results in recycled polyester yarn that is as good as virgin material.

Graphic elements and prints are engineered directly into the kits – never added on top – ensuring “visual storytelling never trumps innovation”.

Breakthrough innovation for athletes

Venkatesh Alagirisamy, Nike EVP and COO, said: “Nike’s new Aero‑FIT kits for the 2026 World Cup mark the first time elite players will compete in uniforms made entirely from textile waste.

“This is breakthrough innovation in service of athletes, proving that high performance and circularity can move forward together without compromise.”

He adds: “From rising temperatures to tougher playing conditions, athletes challenged us to rethink what’s possible.

“Huge appreciation for the Nike teammates and partners whose resilience, creativity, and commitment brought this to life.”
