Headwear in the form, for example, of a baseball cap (1) is provided in its front portion (4) with an inlet aperture (20) with which is associated a baffle (22) whereby in use on the wearer's head, midly turbulent air flow is induced into the cap space (10) by virtue of the baffle (22) thereby to create a cooling effect upon the wearer's head (8). |
