The Spanish national team is surprising everyone in its preparation for the 2026 World Cup by using cutting-edge technology to combat the extreme heat being felt in the United States. The Spanish Football Federation has decided to store the players’ thermal vests… in a cooler, ensuring they are always ready to provide maximum cooling effect during training and matches — an innovative approach that is generating buzz and promises to revolutionize physical preparation in major competitions.
Just days before their debut against Cape Verde in Atlanta, in a Group H match, ‘La Roja’ revealed that they are using thermal vests equipped with a special gel developed by adidas, which is pre-frozen and placed over the players’ jerseys. This technological solution helps keep the torso, abdomen, and back at a lower temperature as the gel melts during physical exertion, reducing the risk of overheating and fatigue. Additionally, the Spaniards are also using innovative boots, which are equipped with the same cooling gel, capable of lowering foot temperature by two degrees in just seven minutes — an invaluable relief given the sweltering heat expected on the North American pitches.

The use of these technologies is not merely a laboratory whim: it is a direct response to the physical challenge that the climate in the United States poses to all teams. With temperatures hovering around or exceeding 35 degrees in several host cities, managing effort and athlete recovery becomes a decisive factor for success, especially in a competition where every detail matters. Spain, the World Champion in 2010, does not hide its ambition to lift the trophy again and is openly betting on science and innovation to ensure flawless preparation.
The Spanish Football Federation took to social media to share a video showcasing the new “CLIMACOOL SYSTEM” in action during training, with the message: “The new CLIMACOOL SYSTEM from adidas arrives at Spain’s training for the World Cup.” The impact of these vests is already being felt among the players, who do not hide their enthusiasm. Sources close to the national team state that the feeling of freshness “makes all the difference in performance and recovery.” Lamine Yamal, one of Spain’s young talents, was seen in training wearing one of these vests and confirmed the importance of this technological support, stating that “in a World Cup, there is no room for physical failures.”
Spain’s investment in advanced cooling solutions could be the decisive trump card in a tournament where endurance and recovery capacity will separate title contenders from those who succumb to the heat. The innovation has not gone unnoticed by rivals and could very well set trends for the future of national team football. The Spanish coach has made it clear that nothing will be left to chance: “We have the best team and we can reach the World Cup final,” he confidently stated ahead of the competition’s start.
With the debut scheduled for tomorrow, all eyes are on how Spain will respond on the field, now that it has shown it is prepared to face not only its opponents but also the extreme conditions of the 2026 World Cup. Should the CLIMACOOL technology and innovative recovery methods yield results, it is expected that other teams will quickly adopt similar solutions. For now, “La Roja” leads the race for innovation and promises to give no quarter either on or off the pitch. The football world is watching closely: will this be the difference that takes Spain to glory?
