Nose BandA leather strap that goes over the bridge of a horse's nose to help secure the bridle. A "figure eight" nose band goes over the bridge of the nose and under the rings of the bit to help keep the horse's mouth closed. This keeps the tongue from sliding up over the bit and is used on horses that do not like having a tongue tie used.
