Exclusive Spirit River UV2 enhanced product. Excellent for pike, musky and billfish patterns. These run 6 to 8 inches long and a few even longer. All are UV enhanced over natural bronze black providing a subtle iridescent color. These are perfect for large silhouettes on saltwater patterns and because of the soft nature of these they swim like crazy. These are great for salmon/steelhead hackle. But even better for pike or articulated monster flies.
