This is super-soft, pre-tapered synthetic fur that will give any pattern incredible action in the water. It boasts life-like material for bait fish imitations, streamers and various attractor patterns. It works well when tying with epoxies and can be easily marked with indelible marking pens for a more realistic, fish-fooling presentation. Polar fibre will hold it's shape in the water, eliminating the pulsing effect that you get with flies tied with natural materials. It is virtually indestructible and dries quickly.
