  G suit \G suit\ G-suit \G-suit\ n. [gravity + suit. 1944[MW10]]
     (Aeronautics)
     A suit worn by aviators and astronauts, designed to
     counteract the effects of high accelerations experienced in
     aerial maneuvers, in particular to avoid unconsciousness;
     called also {anti-g suit}. It exerts force on the abdomen and


     legs to prevent blackouts by counteracting the tendency of
     blood to accumulate below the heart, thus reducing the supply
     to the brain, when the forces due to acceleration are
     directed from head to toe.
