An open-face helmet is recognisable by the lack of its chin bar. The helmet is fully open at the front and bottom. That gives the helmet a unique look. The helmet simply covers a smaller part of the head and face than a full-face helmet. Modern open face helmets often have longer visors that go down as far as the chin. Retro open face helmets often do not feature a visor at all or only a small visor in front of the eyes.
