Zoo Cougar is a large, high-profile streamer designed to imitate bulky baitfish and trigger aggressive predatory responses. Its stacked deer hair head creates significant water displacement, pushing pressure waves ahead of the fly. The spun and clipped head also causes the fly to dive and rise during retrieves, adding erratic motion. A flowing tail provides secondary movement and softens the overall silhouette. The broad profile remains visible in low light and stained water. Durable hair construction maintains shape through repeated casts and strikes. Overall, the pattern emphasizes bulk, motion, and strong predatory stimulation.
