These high-quality CDC Puffs are softer and much suppler than regular CDC feathers. Our Puffs have a multitude of very small dense fibers extending from the shaft of the feather which allows them float high like an indicator or cork. CDC Puffs are perfectly suited to emerger patterns and are ideal for Pale Morning Duns (PMD) and Blue Winged Olives (BWO) wings. Also excel when used for parachute posts on Adams patterns. 36 pack.
