Hareline Cul De Canard 1gr The Duck's Gift to Dry Fly Perfection Cul de Canard—French for "duck's bottom," which sounds far more sophisticated than what it actually is. These aren't just any feathers; they're the naturally waterproofed plumes from around a duck's preen gland, pre-treated by nature's own oil slick. Why CDC is Magic (Science, Really) While other materials sink faster than your buddy's back cast, CDC floats like it's got a personal vendetta against gravity. The microscopic barbules trap air with the efficiency of a thousand tiny life preservers, keeping your flies riding high without a drop of floatant. What You Can Tie Emergers: CDC is the go-to for that half-in, half-out silhouette that drives trout wild Dry Flies: Wings, hackles, or full bodies—CDC does it all with natural buoyancy Mayfly Patterns: Duns, spinners, and everything in between Caddis: Wings that look like they just hatched Midges: Delicate enough for the tiniest patterns The Details Each 1-gram package contains premium CDC feathers in natural colors. That's enough material to tie dozens of flies that'll fool even the most selective risers. Pro tip: Don't over-handle these feathers—the natural oils are what make them work. And whatever you do, don't use floatant. That's like putting training wheels on a Ferrari.
