A smaller, denser, more marabou-like version of traditional Cul-De-Canard, our CDC Oiler Puffs from Hareline have proven a favorite for adding lifelike gills on nymphs, wing tufts on emergent wet flies, and so much more. Available in a wide selection of buggy colors certain to please, try some Hareline CDC Oiler Puffs in your next batch of trout flies.
