The coolest fly patch you'll ever own. The innovative tube design hangs from your lanyard or can be attached to a zinger, and allows airflow to quickly dry flies. The patch can be opened up to be used as a minimalistic fly box and the tough polycarbonate shell protects your flies when pushing through heavy brush and shrubs. A patent pending slit silicon insert holds flies tightly, while handy magnets on each wall catch flies that you simply drop into "the tube" when you're in a rush. Holds between 12-20 flies, depending on size.
