Beyond the race suit and helmet, an F1 driver kit is far more complicated. Safety is of utmost importance because the driver can be in any dangerous situation at any time. Hence the driver’s kit has to stand up to rigorous testing. Luckily, gone are the days of the five-layer fireproof suits introduced in 1979. Instead, F1 Driver Kits are lighter but more durable thanks to the utilization of Nomex.
Nomex is an artificial lab-tested fiber that’s used to create most of the components of a driver’s suit. It has to satisfy stringent criteria. It’s tested against flames of 600° – 800° Celsius, It must resist ignition for 10 seconds. The internal temperature cannot exceed 41° Celsius for 11 seconds.
Inner-wear
The innerwear consists of their race socks, pants, and shirt. This is the inner layer worn under the race suit. It’s a relatively thinner layer of Nomex fiber clothing. The pants and socks are plain without any corporate logos. The shirt, on the other hand, consists of corporate logos printed on it. These innerwear pieces make it very hot and uncomfortable for drivers. However, it’s a small price to pay in terms of safety.

Racesuit
The race suit is the exterior suit visible to us. It’s the driver’s first line of defense against fires. It’s a multi-layered Nomex suit. Even the suit’s zip has to withstand the heat that it could potentially be exposed to. At one point, sponsor logos used to be sewed on with fireproof threads. That practice has been abandoned in favor of printing corporate logos, saving half a kilo of weight.
According to the FIA, each race suit has 15 sessions of washing and dry-cleaning before being tested. The testing criteria are strict. Only suits which pass the tests are finally allowed to be worn by the driver and pit crews.
Despite being fire-resistant, they are light and breathable. It helps sweat escape, as drivers are known to sweat several kilos over the course of a race.

Gloves and Boots
The gloves and boots of the driver are made to different specifications over the race suit and inner-wear. Despite both being fireproof, they are relatively thinner. This is to enable the driver to improve their performance during the race.
A thin glove allows them to feel the vibrations of the steering wheel easily. It allows them to make minute adjustments to their race approach. The gloves are made out of Nomex and thin leather around the palms, to assist drivers with steering.
The boots are soft and made of leather. The rubber soles used are thinner, to enable a driver to feel the pedals better. It also provides a good surface and minimizes the risk of their foot slipping against the pedals.
The possible other use of the F1 driver boots is utilized by Daniel Ricciardo. The Australian is famous for drinking his podium champagne from his boots after a race.

Crash Helmet
The Driver’s crash helmet is the most visible and customizable part of the kit. The helmet has to be tough and is subject to rigorous tests. The materials used include Carbon Fibre and other fire-proof materials. Despite being layered, it’s surprisingly light at 1.2 kilos. Lighter helmets add less G-force whiplash during a race. Simultaneously they are strong to withstand large impacts.
Every helmet is a custom fit for each driver. Not only does it add comfort for them but improves overall safety. A custom-fit helmet is harder to slide during an impact. Also, gaps for debris or flames to enter are minimized.
Head and Neck Support (HANS) Device
HANS is a major innovation in safety. It’s a U-shaped device sitting on the shoulders made of carbon fibre. It has an elastic band to connect it with the helmet. The primary focus is to restrict neck movement during an impact to prevent skull fractures.
Price of the suit
Because of the safety procedures and the research, it has to go through, the suit costs Rs. 3,00,00($4000). In the whole season, the drivers need more than 15 suits for the races.
