Hook & Hackle, A Name You Can Trust
Cul de Canard, or CDC, as it is commonly referred to, is a finely-fibered duck feather with unique floating capabilities. French for "Duck Bottom", CDC is buoyant due to its natural oils and does not require additional floatants. CDC is often used for tying emergers and dry fly patterns.
These puffs can be stacked and tied in as a wing; spun into dubbing loops or used as a dubbing material.
