This dubbing is made of the finest polypropylene mixed with antron fibers. Thus it is appropriate for making even the smallest fly bodies. The 6 dubbing types have been determined by the most common body colors of sedges and caddis flies. Thus they cover almost the entire spectrum of color shadings that occur. Additionally, the dubbing consists of a blending of a variety of colors since, even in nature, the body of a fly is not monocolor but rather reflects varying light and dark tones.
