Overalls and undies

The driver’s overalls look similar to a baby’s romper suit. They zip up the front and cover their arms and legs. These suits are made of a special material called Nomex that is fire-resistant. The sport’s governing body, the FIA, demands that the material used must protect a driver from a fire of up to 700 degrees centigrade for at least 12 seconds – and the sponsors’ logos have to comply with this as well.
To increase the drivers’ protection, they also wear T-shirts, underwear and socks all made of Nomex. All of this makes it very hot in the car for the driver, but it is a small price to pay in the quest for safety.
