Overview
Hareline's CDC28 is a small pack of cul de canard (CDC) feathers dyed Blue Wing Olive, weighing about 0.1 ounces and sold as a single count pack for fly tying.
CDC feathers come from a duck's preen gland and carry natural oils that help them float, which is why fly tyers reach for them on dry flies and emerger patterns rather than streamers. The Blue Wing Olive dye ties it to BWO mayfly imitations, a common trout pattern.

Who it's for
Fly tyers building BWO dry flies or emerger patterns. It is not intended for spin or bait fishing, since it is a raw tying material rather than a finished lure.
Pros and cons

- Blue Wing Olive dye matches common mayfly hatches
- Sized for precise dry fly and emerger work
- Very small quantity at 0.1 ounces

Performance notes
CDC feathers retain natural preen oil that helps finished flies float without heavy floatant, and the fine barbules give patterns a soft, mobile look in the water that stiffer hackle cannot match.
