1. A helmet comprising:
a shell including an outer surface and an inner surface, the shell defining a shell ventilation aperture passing from the outer surface of the shell to the inner surface of the shell;
an inner liner securable within the shell, the inner liner defining an inner liner ventilation aperture that aligns with the shell ventilation aperture when the inner liner is secured within the shell, the inner liner further defining a recessed track in an inner surface of the inner liner; and
a ventilation control including a slider plate and a boss disposed on an upper surface of the slider plate, the boss configured to frictionally engage the recessed track and to be reversibly displaced along the recessed track from a first position in which the slider plate blocks a flow of air through the inner liner ventilation aperture to a second position in which the slider plate permits the flow of air through the inner liner ventilation aperture, the slider plate configured to be reversibly displaced between the first position and the second position by a force applied upon a lower surface of the slider plate from within an internal volume of the helmet.
