Wapsi Marabou is a turkey body feather. It has a fluid, lifelike breathing action that makes it incredibly useful for fly tying. Marabou can be used for streamers, tails, bodies, throats, collars, wings, and backs. Wooly Bugger 1/8 oz. has a shorter fiber and a larger, stiffer center shaft, making it a good choice for wooly buggers.
