Hareline Dubbin UV2 Select CDC Feathers are premium fly-tying material designed to add lifelike flotation and subtle UV-enhanced flash to dry flies, emergers, and soft-hackle patterns. These selected CDC (cul de canard) fibers are treated with the UV2 dye formula to improve visibility during hatch conditions and help your patterns read naturally on the water. Key Features UV2 Dyed: UV-enhanced fluorescence increases visibility in low light and during blanket hatches. Premium CDC: Natural CDC fibers float like a cork and undulate with lifelike motion to imitate natural insects. Selected Quality: Carefully selected and stacked to protect quills and ensure consistent fibers for precise tying. Assorted Colors: Wide range of trout-proven colors (Rust, Black, Pale Yellow, Light Dun, etc.) to match local hatches. Versatile Use: Ideal for dries, emergers, soft hackles, and delicate surface patterns used in trout and freshwater fishing. Fly tiers choose Hareline Dubbin UV2 Select CDC for the combination of natural buoyancy and UV-pop that makes flies ride high and look alive. Use these feathers to finish emergers, add soft-hackle bodies, or create tiny dry flies that need subtle movement and flotation. The UV2 treatment (Spirit River UV2 formula) helps attract attention in overcast conditions and heavy hatches, while Hareline's selected stacking protects delicate quills during storage and tying.
