Dry your soaked CDC fly patterns quickly and naturally. Amadou, a spongy material derived from a natural tree fungus (Fomes formentarius), has amazing fly-drying qualities. To use, simply squeeze your drowned dry fly in between the two patches and all the moisture is sucked out. You are now ready for action. Not just for CDC flies, the Amadou Fly Dryer will also dry larger flies and prepare the fly to be redressed with floatant. Leather cover protects the Amadou. 2" X 3".
