In 1979, Lauda, along with Carlos Reutemann and Mario Andretti began wearing racing suits that were made of five layers of fire-retardant material that was also used by NASA for astronauts' suits.

Nomex is a synthetic fiber that allows a driver to survive in 850 degree Celsius heat for at least 35 seconds.
