Spirit River continues to lead the way in UV2 technology. We have used a double dye process to give all our unique UV2 materials and flies the added UVF/UVR ultraviolet wavelengths. We all know UV Fluorescence which is so common on everything from street signs to bass lures. UV Reflectance is a spectrum of wavelengths humans can not perceive yet is extremely common in the animal and insect world. UVR allows mayflies to find mates, and bees to find flowers. Many male birds and bugs have a strong natural UVR signature.
