Football equipment was long a matter of boots, shirts and materials. For the 2026 World Cup, adidas is now bringing a system into focus that is designed to work directly on the players’ bodies.
The 2026 World Cup will be played in the United States, Canada and Mexico. In cities such as Miami, Dallas or Monterrey, temperatures during the tournament could rise well above 30 degrees. adidas is responding with a new CLIMACOOL SYSTEM designed to help players cope better with heat and humidity.
The system consists of a cooling vest, an insulating jacket and a cooling cover for the football boot. The vest is worn over the shirt and uses a gel that is frozen before use. It is designed to cool the upper body, abdomen and back. The jacket helps keep the cold closer to the body for longer.

According to adidas, the system was developed in close collaboration with Manchester United, Juventus and Arsenal. Feedback from players and medical teams fed directly into testing and further development.
adidas’ CLIMACOOL SYSTEM for the 2026 World Cup
adidas says the vest and jacket can reduce core body temperature by up to 0.5 degrees Celsius and skin temperature by up to 13 degrees Celsius. The cooling cover for the football boot works at the foot. It is placed directly over the boot and is designed to reduce overheating and swelling. Within seven minutes, it is said to lower foot temperature by two degrees Celsius, without affecting ball feel when dribbling, passing or shooting.
The technology has its origins in another high-performance environment. It is based on solutions originally developed for drivers of the Mercedes-AMG Petronas Formula One Team. For football, the system was adapted, including a front zip on the vest so players can put it on and take it off more easily.
For the 2026 World Cup, the CLIMACOOL SYSTEM will be made available to all 14 adidas partner federations.
On the pitch itself, little of the CLIMACOOL SYSTEM will be visible. It is designed to help players cope better with heat and humidity around the game. At the 2026 World Cup, cooling will become part of load management.
