Spirit River® continues to lead the way in UV2 technology. They've used a double dye process to give all their unique UV2 materials and flies the added UVF / UVR ultraviolet wave lengths.
UV Florescence is common on everything from street signs to bass lures. UV Reflectance is a spectrum of wave lengths 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.
