Neck Hackles have large wide feathers that make them an ideal choice for tails on dry flies, streamer wings, bass flies, and saltwater patterns. The hackles are strung together for convenience in selecting the right feather. Standard Neck Hackle is 4 to 5 inches in length (100 to 127 millimeters). Premium Neck Hackle is 5 inches or longer in length (127 millimeters).
