Hartwick’s Hoser in Black Blue is a slick steelhead tube fly. Flowing marabou, grizzly hackle wings and subtle flash underneath are the perfect combination of all that steelhead love to eat. The tungsten conehead adds weight and is hidden just behind where the marabou is tied in. It also acts as a platform to keep the marabou from collapsing in the water. The fly is approximately 2 3/4″ in length and comes ready to fish with junction tubing and hook.
