Adidas has unveiled its futuristic CLIMACOOL+ range at Wimbledon, featuring 3D embossed shirts designed to keep tennis players cool during the ongoing heatwave. With temperatures exceeding 30°C, the technology aims to counteract the negative impact of heat on performance, including reduced serving power, hitting consistency, and cognitive function.
How the 3D fabric works
Margherita Raccuglia, Director of Athlete Performance at Adidas, explained that the 3D fabric construction maximizes the air gap between the shirt and skin, allowing better air circulation. This enhances evaporative cooling, reducing wetness and skin temperature. "When you do that you allow for more air to circulate. As the air can better circulate, the evaporative efficiency and cooling go up," she said.
Players using the technology
French Open champion Alexander Zverev and Felix Auger-Aliassime have worn tailored versions of the shirts at Wimbledon. Zverev reached the semi-finals, while Auger-Aliassime lost a tight five-setter to Novak Djokovic in the quarter-finals. Female stars Maria Sakkari, Elina Svitolina, and Karolina Muchova also use CLIMACOOL+ technology, though without the 3D shirts, instead featuring power mesh, laser-cut perforations, and heat-sealed finishes.
Heatwave challenges at Wimbledon
The heatwave has been a major talking point, with players battling through long matches. Raccuglia noted that high body temperature compromises physical and cognitive performance, including decision-making and reaction times. "Wet cling" – when sweat makes the shirt stick to the body – also restricts movement.
Development and availability
The technology was developed through climate chamber testing, thermal mannequins, and real-match simulations. Adidas plans to roll out the cooling designs across 2027 and 2028, with versions available for club players. The brand says the unique look "screams technology" and that players are excited to wear it.
