Polar Dub by H2O is a super fine synthetic dubbing with slightly longer fibres, which are ideal for brushing. You can dub it onto the hook shank directly or use the split thread or dubbing loop technique. This dubbing can be used for tying outstanding shrimp and small baitfish patterns for coastal fishing. But, the discreet gloss of this soft synthetic dubbing is also extremely nice for all kinds of salmon flies and nymphs. A small amount of flash fibers adds some extra attraction to the material.
