EP Fibers are 10 inches (250mm) in length, amazingly translucent, and have an action between marabou and BUCKTAIL. They come in a great range of colors and are perfect for imitating large baitfish such as Herring, Mullet and Mackerel as well as 1” to 2” baitfish. Large flies tied with those fibers are a dream to cast up to 90’ because the first back cast removes all the water from the fibers. THEY DO NOT ABSORB WATER. Use your imagination and there is no limit to the flies you can create with EP Fibers.
