A helmet can comprise an upper-body and a lower-body nested within the upper-body. An opening can be formed within a front portion of the helmet and disposed between an outer surface of the upper-body and an inner surface of the lower-body. A first magnet can be encased within the upper-body or the lower-body and adjacent the opening. A shield can comprise a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably coupled to the first magnet. The first magnet and the second magnet can be self-aligned in direct alignment with eyes of a user. A third magnet can be disposed above the first magnet and aligned with the second magnet on an outer surface of the helmet out of sight from eyes of the user.
