Spirit River UV2 Coastal Deer Hair- This hair is great for small dries- comparaduns, sparkle duns and caddis flies.
The tips of this hair taper to a sharp point and have a short overall length with slightly larger diameter butts. There is still some hollowness to the hair at the tips despite its shortness. Hair with long wispy tips may be useable for larger-sized flies, but on smaller 18s and 20s, where the proportionate wing length becomes much shorter, the wispy tips provide no floatation and do not flare as well as hair with more diameter. The butt ends of Coastal Blacktail Deer hair is a larger diameter so it flares on the shank when you tie it down, spreading the tips in a nice arc across the top of the shank. This helps the fly float better.
What is UV2 Technology?
It is a double dye process to give all of their UV2 materials and flies added UVF/UVR ultraviolet wavelengths. UV Florescence is used on everything from street signs to fly tying materials. UV Reflectance on the other hand is a spectrum of wavelengths humans cannot visually see; yet it is extremely common in the animal and insect world. UVR allows mayflies to find mates, and bees to find flowers. Fish can see it, and they love it. UV materials and flies are becoming much more popular within the fly-fishing world because of the success they bring them while on the water.
