G-suit

MSF830 Anti-g Suit trousers and cummerbund fitted over a flying suit

A g-suit, or anti-g suit, is a flight suit worn by aviators and astronauts who are subject to high levels of acceleration force (g). It is designed to prevent a black-out and g-LOC (g-induced loss of consciousness) caused by the blood pooling in the lower part of the body when under acceleration, thus depriving the brain of blood.[1] Black-out and g-LOC have caused a number of fatal aircraft accidents.[2]
