Rabbit mask is one of the most used materials when tying artificial flies. It produces some of the best dubbing. The combination of small fine sharp hairs with a shine (guard hair) and the delicate undercoat (undercoat) mixed as a dubbing is used on many flies. Since the mask has the finest rabbit fur (around the nose, eyes and entire ears), the dubbing obtained from it allows it to be used even on a very small number of flies. An absolute classic for the use of the rabbit mask is the world-famous "Rabbit Ear Nymph".
