RIO’s Morrish Still Stone is a highly realistic foam stonefly pattern designed to imitate adult salmonflies and golden stones sitting naturally on the water’s surface. Its low-riding profile, lifelike silhouette, and durable foam construction make it deadly during Western stonefly hatches when trout are keyed in on natural presentations. The Still Stone excels along grassy banks, slow seams, and soft edges where big fish are looking for an easy meal. A proven dry fly pattern for technical trout during peak stonefly season.
