Corrected entry: This is only in the "extended version" of the video, as far as I know. When the Enterprise is inside VGer, Spock leaves the ship and flies around in a spacesuit. He exits and re-enters the ship in a white spacesuit with a round helmet, but is shown flying around in an orange suit with a conical helmet.

Correction: Actually, it's Kirk in the white suit. There was a sequence where the pair of them investigated V'GER.
