A venting system for a sports helmet has venting openings wherein at least some of the venting openings have covers that at least partially cover the venting openings. By tilting about an axis of rotation the covers partially or completely release the venting openings. Upon actuation of the cover, one end of the cover is lifted above the surrounding helmet surface while the other end of the cover is lowered below the level of the surrounding helmet surface.
