G-suit

A G-suit, or gravitational suit, is a type of pressure suit worn by pilots and astronauts to counteract the effects of acceleration forces, particularly during high-speed maneuvers or in higher gravity environments. The primary purpose of a G-suit is to prevent a condition known as "G-induced Loss Of Consciousness" (GLOC), which occurs when blood pools away from the brain due to high G-forces, potentially leading to unconsciousness.
