Ultra Dense CDC Feathers

Super Select CDC

Cul de canard or CDC feathers are naturally buoyant and have a delicate, intricate structure that makes them great to use as wings one dry flies and emergers. They give both a lifelike appearance and aid in floatation, and they're easy to tie in and work with. CDC can also be a great material for wet flies and nymph legs, and can even be wound on as a dry-fly body. These are selected grade feathers.
