The Solitude Signature Intruder is a highly effective fly pattern designed primarily for targeting steelhead and salmon. This fly is known for its large, eye-catching silhouette and intricate design, which includes materials like ostrich hackle and heavy dumbbell eyes to ensure it sinks quickly and swims naturally in the water. Its design allows it to be cast easily despite its size, making it a favorite among anglers for both winter and summer steelhead fishing.
