There is described a hollow visor capable of being removably attached to a safety helmet of the type used by motorcycle riders. The visor is filled with water and sealed. One end of small tube extends into the hollow portion of the visor with the other end of the tube removably attached to the open face portion of the visor, thereby allowing the user to hold the open end of the flexible tube in his mouth. The visor is particularly useful for racing drivers by allowing the user to keep his mouth moist without taking his hands off the controls. The water will not leak from the visor since it is sealed and must be drawn out by the user.
