New Technology for the Spanish National Team's Clothing in the World Cup

Adidas has introduced a new technology as part of the preparations for players of the national teams participating in the 2026 World Cup, including the Spanish national team players. This is through a system called CLIMACOOL SYSTEM, which is adopted in playing environments with high temperatures.

This system, according to the information provided, is used as part of a physical preparation routine, aiming to help regulate body temperature during physical activity. It combines a cooling vest and an insulating vest that work together on the upper body.

According to the available data, the system can help reduce the body's internal temperature by up to 0.5 degrees Celsius and may decrease skin temperature by up to 13 degrees Celsius under controlled conditions.

The system also includes a cooling cover for shoes designed to reduce the temperature of the foot area, with the possibility of lowering it by about two degrees Celsius within a few minutes. This usage is incorporated into physical preparation and recovery protocols according to the team's needs and timing.

This system is part of performance support tools in professional football when playing in hot weather, and it is available for teams wearing Adidas apparel during the tournament.
