Spirit River UV2 Goose Biots — UV-Enhanced Tailing & Antenna Material for Nymphs & MoreGoose biots are one of the most versatile and widely used materials in nymph tying — short, tapered quill fibers that produce perfect tails, antennae, and segmented bodies on stoneflies, hellgrammites, PMDs, and countless other patterns. Spirit River takes them a step further with their UV2 double dye process, adding both UVF and UVR wavelengths that make your flies more visible and more attractive to fish than standard biots alone. The multi-color Packs give you a range of shades to cover a variety of patterns in a single purchase.UV2 Technology Explained UVF (Ultraviolet Fluorescence) — the fluorescent wavelength that fish see in brighter, more vivid colors than the human eye. Flies with UVF are visible to fish at greater distances, even in low light and off-color water. UVR (Ultraviolet Reflectance) — a UV light spectrum largely invisible to the human eye but clearly visible to most fish and insects. UVR mimics the natural UV signatures of aquatic insects, triggering instinctive feeding responses. Key Features Short, tapered quill fibers — ideal for tails, antennae, and segmented body wraps Spirit River UV2 double dye process — UVF + UVR wavelengths built into every fiber Multi-color Packs available — multiple colors per pack to cover a variety of patterns Perfect ForStonefly nymphs, hellgrammites, PMD nymphs, BWO nymphs, and any pattern where a short, tapered biot fiber adds a realistic tail, antenna, or segmented body with built-in UV attraction.
