Well, there is the Nomex™ underwear. Like thermal long johns, only made from Nomex™. And socks and the balaclava made from Nomex™.
Then the suit is usually three layers of Nomex™, some sanctioning bodies require more, like 5 or 6 layers. It is like wearing a suit made from a moving blanket.
Then consider the race car is quite spartan. In recent years much has been done to deflect the heat away from the driver, and provide some insulation from it. But still, there isn't much to reduce it. And 800 horsepower race engines generate a considerable amount of heat.
The brakes also generate a lot of heat.
The tires also make heat as they scrub around the track at speed.
Like sitting in an oven.
The track gets hot in the heat of the day, and radiates heat up into the cars too.
So yeah, it gets warm in a Nomex™ suit.
