This pouch contained the oxygen masks and hoses available to the Apollo 11 astronauts in the event of an emergency. In order to avoid having lose items floating around the spacecraft, the masks and hoses could be coiled and stored in this beta cloth bag.
NASA transferred this bag to the Musuem with other Apollo 11 equipment in 1970.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
