Anti-g suits, also known as G-suits, are specially designed garments worn by pilots and astronauts to prevent the occurrence of negative effects caused by high G-forces. These suits apply pressure to the legs and abdominal regions, forcing blood back towards the head to prevent fainting or blackouts. Synonyms for anti-g suits include gravity suits, high-G suits, pilot suits, and space suits. The use of these suits is essential for high-performance aviation activities such as air racing, fighter jet flying, aerobatics, and space exploration. The development of anti-g suits has helped improve the safety and well-being of pilots and astronauts, ensuring they can perform their duties at high levels.
