Training suits were identical to those worn during the missions. This suit is an A7-L model, in the intra-vehicular configuration, which is the model worn by the Command Module Pilot.
NASA transferred this object to the museum in 1977.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
