A brow pad for the headband of a protective helmet or similar headgear is ultrasonically welded or similarly joined to itself through openings defined through the headband. By joining the brow pad to itself through the headband, the brow pad remains secured to the headband even after extensive usage. Furthermore, the openings defined through the headband provide some measure of ventilation and evacuation of accumulated moisture from the brow pad. Finally, by joining the brow pad to itself and through the headband, there are pockets of air that are trapped between the joined portions of the brow pad, which serve as air-filled "pillows," providing some measure of comfort to the wearer.
