Detail of the suit's torso.

Along the top of this photo are the suit's nametag and former location of the NASA patch.

The upper-most chest connector is the opening for the communications and bio-med connector. The red connector is the oxygen outlet connector, and the connector to its right is the oxygen inlet connector.

I am uncertain as to what the two small, blue connectors are at the waist, as they do not appear on the G4C actually used in flight (in fact, these connectors do not appear any other photos of G2C suits which I've seen).
