Hadjar and Verstappen criticise the system
Isack Hadjar believes cooling vests should be removed, arguing that physical exertion is part of Formula 1. Motorsport.com published his position on 8 October. Max Verstappen says he does not need the system and that its tubes restrict his freedom of movement. These are the drivers' assessments.
Ocon sees a benefit, with limits
In Thursday's FIA press conference, Esteban Ocon describes a physical benefit but says cooling does not last throughout the race. His estimate of around 40 minutes reflects his own experience, rather than a guaranteed duration for every team. Franco Colapinto prefers not to wear the system because of discomfort, while Fernando Alonso supports leaving the choice to teams and drivers.
The heat brings the debate back into focus
Reuters reports that George Russell supports using the system, in contrast with Verstappen's scepticism. The agency confirms heat-hazard conditions have been declared in Singapore. The debate about comfort and effectiveness remains separate from the sporting schedule.

APEX interpretation: personal preferences deserve coverage without becoming general conclusions about safety. Comparing solutions would require technical data and comparable test conditions. This article tracks the views expressed; the Singapore guide separately maintains the schedule and official warnings.
