Isack Hadjar calls for Formula 1 to ban cooling vests because racing should be physically tough.

Red Bull driver Isack Hadjar believes cooling vests should be banned from Formula 1, arguing that extreme physical challenge remains an important part of motor racing. The topic resurfaced at the Bahrain Grand Prix in Malaysia due to extreme heat and humidity at Sepang International Circuit, with mixed feedback from drivers about the equipment's effectiveness.

Hadjar took a clear position against artificial cooling aids, stating they have no place in Formula 1 because racing is supposed to be tough. His teammate Max Verstappen agreed the cooling vest was not needed, explaining that cables limit driver movement and the system doesn't work effectively for a full race distance.

The cooling vests pump cool liquid around the body through tubes in fireproof tops worn under race suits, but effectiveness diminishes as cockpit temperatures rise and heat the liquid in the tubes. When heat hazards are declared, teams can choose cooling vest systems or carry ballast to avoid weight disadvantages.
