Spirit River's UV2 strung saddle hackle feathers are among the best quality on the market. These beautiful UV2 dyed fly tying hackle feathers are enhanced with UV fluorescing and reflecting properties, increasing the visibility and giving off a natural color spectrum more visible to fish. Great for an added advantage when fishing in dark and murky conditions. These hackle feathers are long and easy to work with. Use them for tying streamer tails, wings, throats, collars, and palmered hackles on larger flies. Perfect for steelhead and Atlantic salmon flies, as well as bass and saltwater streamers. You'll love them and the fish will too!
