This bladder was used during the Shuttle era and fit under the pressure glove of the Extravehicular Mobility Unit (EMU) spacesuit.
The pressure glove is a flexible gas-retaining device which locks to the torso limb suit. It consists of a bladder, a fingerless glove, inner and outer covers, and a restraint system. The bladder is moulded from a cast of each astronaut's hand. The bladder core, made of nylon tricot dipped in a Neoprene compound, is exposed at the inner thumb and fingertips to give the astronauts feeling in those areas.
NASA transferred this glove to the Museum after the end of teh Space Shuttle program.
