No. 86 UV Tenkara Kebari #12 Size, Barbless, Pack of 30 This fly features a body made of eye-catching UV material and peacock herl, with grizzly and olive hackle. The UV material comes in three colors: green, pink, and orange. Both Iwana (white-spotted char) and Yamame (cherry salmon) respond well to this fly, and I use it as one of my main flies throughout the year. This is a surface-level fly.
