Spirit River UV2 Jailhouse Marabou

SPIRIT RIVER UV2 JAILHOUSE MARABOU. Spirit River continues to lead the way in UV2 technology. They use a double dye process to give all their unique UV2 materials the added UVF/UVR ultraviolet wave lengths. UVF is the fluorescent wavelength. Fish can see this spectrum in brighter colors than we see. This allows fish to see flies at a much greater distance, even in varying light and water conditions. UVR or Ultra Violet Reflectance, is a UV light that cannot be readily seen with the human eye in some wavelengths, but it can be seen by most insects and animals. Ideal for fly fishermen or spinning anglers making streamers.
