George Russell, who drives for the Mercedes Formula 1 team, sparked debate recently after hinting that the FIA ought to intervene and mandate the use of cooling vests during sweltering Grands Prix to protect teams from their own competitive instincts.
The well-being of competitors in high-temperature environments has been a major talking point since the 2023 Qatar Grand Prix. During that Doha event, which took place in October before its schedule was adjusted to a cooler December slot, numerous drivers suffered from severe heat fatigue.
To address this, the governing body alongside the F1 grid initiated studies to optimize cockpit airflow and driver cooling under intense heat. This effort culminated in the creation of an active cooling garment that pumps water via a network of tubes, designed for driver use during extreme thermal stress.
A formal “heat hazard” is officially designated by the FIA at the onset of a race weekend if forecasted ambient temperatures for any track session are expected to go beyond 31 degrees Celsius.
This week’s Grand Prix, uniquely hosted in Malaysia despite its Bahrain branding, marks the third heat-hazard event of the 2026 championship, and a fourth occurrence is anticipated for the upcoming round in neighboring Singapore.
This situation led Russell to admit his preference for utilizing a specialized cooling setup, though he noted that the Mercedes squad chose not to invest in building such a system.

“Our team is skipping the cooling vest as we haven’t allocated the necessary development to make it sufficiently reliable,” Russell explained to The Times while in Kuala Lumpur.
“It is highly effective when fully functional, and I’d certainly prefer to utilize it for both this and the upcoming race weekend. However, the team essentially presented it as a trade-off, asking me if we should invest funding there instead of on raw car speed.”
This prompted Russell to advocate for regulatory action from the FIA to save the squads from their own performance-driven sacrifices: “I believe the governing body should take control by either offering budget cap allowances specifically for this, or commissioning an outside supplier to manufacture a standardized solution for the grid, with teams funding it. Ultimately, it is something we all ought to be utilizing.”
Although some commentators have framed this as a conflict between Russell and his engineers, or suggested he is being subjected to harsh conditions against his will, the actual situation is far more straightforward.
At first, the FIA contemplated enforcing compulsory wear of the garments during declared heat hazards. However, the baseline model failed to win over the drivers, with several reporting that its cooling benefits faded after just a few laps, turning the vest into uncomfortable dead weight. Consequently, wearing the device remains discretionary; those opting out must compensate by carrying an equivalent 0.5kg ballast weight in their vehicles.
Teams retain the liberty to engineer custom variations under specified guidelines to boost cooling performance and driver ergonomics. Nevertheless, because heat hazards occur so infrequently over a championship calendar, most outfits do not view it as a wise use of technical resources, especially since subsequent races have not matched the extreme conditions witnessed at Qatar in 2023.

Given the widespread rejection of a mandatory rule by the competitors, the FIA has remained content to leave the setup voluntary, allowing individual squads to determine their approach. Consequently, there seems to be very little interest in reopening this discussion.
As pointed out by Russell during his remarks, dedicating valuable staff hours and budget caps to garments that are rarely used would divert focus and capital away from making his W17 chassis faster.
With Mercedes locked in a tight development race to maintain its position against rivals like McLaren, Red Bull, and Ferrari, and given that the matter is currently viewed as a question of driver comfort rather than critical safety, it is obvious which objective takes precedence.
