The brand new wearable-tech shirts designed to maintain drivers cool in races in excessive warmth will likely be non-obligatory for opponents within the 2025 Method 1 season, Motorsport.com understands.
The units are being launched as a part of the FIA’s response to the occasions of the 2023 Qatar Grand Prix, the place Logan Sargeant withdrew for Williams with heatstroke, then Alpine driver Esteban Ocon vomited in his helmet and Aston Martin racer Lance Stroll briefly handed out.
As first reported by Motorsport.com, the preliminary considering on the subject was to aim to introduce an ersatz air-conditioning unit to chill automobile cockpits.
However this was deserted as a result of complexities arising in adapting such equipment, and so utilising present wearable-tech – such because the Cypher Professional Micro Cooler produced by Chillout Motorsports (pictured above) – was deemed to be the FIA’s most popular route.
One of many primary challenges to this work was making certain the cooling units complied with the governing physique’s stringent guidelines on hearth resistance for all driver-worn equipment within the occasion of a crash.
The units mix a shirt with practically 50 metres of tubes that pump cooled fluid saved in a devoted field that homes a micro-processor and the know-how wanted to maintain the related temperatures down round a driver’s torso.

This contains defining when the system will must be used – as its use will solely be mandated within the guidelines for the groups to suit it to their automobiles when temperatures attain a sure threshold.
This has now been set at 31C ambient temperature on the FIA sensors positioned round a typical F1 venue (there are 4 climate stations erected at every race), reasonably than being measured on how sizzling circumstances are in automobile cockpits, which might shortly attain 50-60C.
For the 2026 F1 season, the cooling programs will powered by the otherwise organized electrical programs of the brand new automobile designs and can due to this fact be carried always.
However for the upcoming marketing campaign, because the system solely will likely be retro-fitted to automobiles when the 31C mark is reached, drivers have been given the choice of not utilizing it.
The added time earlier than it turns into necessary will even enable additional proof of idea research to be accomplished and for the programs to doubtlessly be additional tweaked forward of 2026.

But when a driver chooses to not put on a cooling vest in 2025, it’s understood they have to nonetheless carry an additional 500g in ballast inside their cockpits to make sure they don’t acquire a aggressive edge by selecting to take this method.
On the Hungarian GP final 12 months, when this subject first surfaced within the wake of the FIA’s dedication to make sure the Qatar farce wouldn’t be repeated, Lewis Hamilton declared “it isn’t wanted”.

“That is Method 1,” he added. “It is at all times been like this. It is powerful in these circumstances. We’re highly-paid athletes. And you have to prepare your arse off to ensure you can stand up to the warmth, finally.
“It is powerful. It isn’t simple, particularly whenever you go to locations like Qatar and Singapore. However I do not suppose we’d like an AC unit within the automobile.”
