F1 drivers want cooling vests banned as Max Verstappen claims “I don’t need it”

Formula 1 drivers are divided over driver cooling vests, with Red Bull's Isack Hadjar calling for them to be banned and teammate Max Verstappen stating he does not need the device. Ahead of the Singapore Grand Prix, where a heat hazard was declared with temperatures topping 31C, multiple drivers raised issues regarding reliability, cables restricting movement, and general comfort.

While optional cooling vests allow systems to circulate chilled liquid, several drivers noted they only function for 15 to 40 minutes before the fluid turns warm. Ferrari's Charles Leclerc and Haas's Esteban Ocon acknowledged physical performance benefits despite technical flaws, while Mercedes opted out entirely to prioritize car development resources under cost cap allowances.
