Credit: © Mark Wade
Status: Operational 1971.
The basic function was the opposite of a G-suit. Instead of pushing blood and fluids away from the legs back toward torso and head, the Chibis suit drew fluid back down to the legs. This was to counteract the tendency of fluids to accumulate in the head in weightlessness.
It was also used post-flight for recovery after long flights. Chibis means 'Lapwing' in Russian. The suit has a mass of 8.7 kg; the vacuum attachment adds another 3.7 kg.
