A g-suit is short for an anti-g suit, a specialized garment worn by pilots and astronauts to prevent loss of consciousness due to high G-forces. It works by inflating bladders around the legs and abdomen, squeezing them to prevent blood from pooling in the lower body. This helps maintain blood flow to the brain during rapid acceleration. Think of it like a body-hugging airbag that keeps you conscious. Pilots need them for high-speed maneuvers.
