Ice Dub is a Mylar-like substance and unlike any other dubbing material of which we are aware, it is able to reflect and refract light in a number of unusual ways. It is super sparkly which makes it very popular for tying nymphs and emergers. Can be used by itself or blended with other materials. In some colors, it appears much like natural animal fibers. In other colors, it adopts a UV halo much like several insect species. In still other colors, Ice Dub has holographic properties like fish scales. Ice Dub is fine textured and fairly easy to tie.
