Dark Olive and Gold with CDC Collar

Dark Olive and Gold with CDC Collar

This dark olive and gold euro nymph is a precise, refined pattern built for tight-line nymphing — combining a natural, earthy olive body with gold flash and a CDC collar that adds a level of realism and movement that few euro nymphs can match. The dark olive body imitates a wide range of mayfly nymphs, caddis larvae, and other aquatic invertebrates that trout feed on throughout the season, while the gold tungsten bead provides the weight needed to get the fly into the strike zone quickly and keep it there through fast, complex currents. The CDC collar is the defining feature of this pattern — the soft, highly water-absorbent CDC fibers breathe and pulse with subtle, lifelike movement in the current, creating a trigger that selective trout find difficult to refuse.
