One variation of a helmet system includes: a shell defining an interior volume and an aperture proximal an anterior end of the shell; a primary visor coupled to the shell and transiently arranged over the aperture; a secondary visor adjacent the aperture, including an elongated translucent member suspended from the shell, and defining a first discrete reflective region on a right side of the elongated translucent member and a second discrete reflective region on a left side of the elongated translucent member; a camera coupled to the shell and defining a field of view extending outwardly from a posterior end of the shell; and a projection system projecting an image onto the first discrete reflective region and onto the second discrete reflective region, the image comprising a subregion of a video frame recorded by the camera, the secondary visor reflecting the image toward the interior volume.
