Air-deflection attachment for an item of protective gear worn on the head of a wearer. The attachment includes a deflector portion of unitary substantially air-impermeable flexible construction for location alongside the face and forwardly from an ear of the wearer, and an attachment portion attached to the deflector portion for releasably attaching the attachment to the item of protective gear. The deflector portion is generally in the form of a vertically elongated aerofoil, for deflecting flow of air past the head of the wearer arising from movement of the wearer in a direction in which the wearer is facing, away from the wearer's outer ear canal opening.
