I think I saw them on a Canadian agricultural site. It looks like a hood that goes clear around under the chin. Covers the ears, opening for the eyes and covers the muzzle to about three inches from the mouth. Sort of like a race horse's eye shield, but more open, since you only have to have it go down under the neck and around the face, under the chin. Does that help? Not really ear muffs.... more like a hood.
