In this piece, Patrick Kilby explores why marabou remains one of the most trusted materials in steelhead flies and how a single pattern—the RIO Marabou Tube—can become one of the most versatile flies in an angler’s box. From fishing it as a standalone pattern to stacking tubes, building squid-style profiles, pairing it with rabbit-strip flies, or reversing the tube to increase bulk, Patrick shows how a simple marabou fly can be adapted to match a wide range of steelhead conditions. The result is a modular approach to fly design that maximizes movement, profile, and on-the-water flexibility.
