An equine mask and sun visor combination that protects the face and eyes of the horse against several environmental insults simultaneously, including insects, water-born particulates and direct sunlight. A second layer of UV-opaque material is added to a first UV-retarding screen layer to form a sun visor disposed to protect the horse's eyes from direct sunlight and precipitation without blocking the horse's vision. The two distinct mask layers are joined in a manner that forms a single equine mask assembly which neither irritates nor discomforts the horse during long-term continuous wear.
