South Africa debuted the new Adidas Climacool cooling jacket in a striking silver colorway at the 2026 World Cup. The look evoked memories of spacesuits.
The Adidas Climacool system is engineered specifically to lower core body temperature and improve heat tolerance in hot and humid conditions - exactly the kind of environment teams face at a summer World Cup in the USA and Mexico. The system consists of three components: a cooling vest, jacket and overshoe, with the vest worn over the player's jersey containing a specialised gel that is frozen before use and slowly thaws to keep players cool as they prepare to take the pitch.
