Summary The degree of sun protection provided by various styles of hat at different anatomical sites on the head was measured using model headforms and ultraviolet‐sensitive film badges. It was found that hats with a small brim, such as the flat cap favoured by elderly male photosensitive patients, provided negligible protection at all sites apart from the vertex and forehead. Peaked baseball‐style caps offer good protection to the nose but are relatively ineffective at other sites on the face. Hats with a wide (>7.5 cm) brim are necessary in order to provide reasonable protection factors (>3) around the nose and cheeks.
