A subtle but deadly size 16 midge. The Duracell is a combination of purple ice dubbing and a CDC Collar, this jig nymph is built to fool even the pickiest fish. The CDC collar gives it just the right amount of life, while the jig hook and tungsten bead keep it riding hook point up—perfect for tight-line nymphing or dropping in deep pools. In slow winter drifts or fast runs, this fly just works.
