EP™ TRIGGER POINT INTERNATIONAL FIBERS. Enrico Puglisi Trigger Point Fibers are specifically designed by Enrico Puglisi and innovative Australian fly fisherman and fly designer, Mick Hall. These fibers were created to "match the hatch" of a multitude of wing and body colors found in the insect world. The wings and bodies of Mayflies, such as March Browns, Sulphurs, Hendricksons, Green Drakes, Blue Winged Olives and the fabled Pale Morning Dun, can be easily matched with the use of these fibers. They provide thin profile bodies on flies, making traditional dubbing obsolete. You can select an EP™ Trigger Point Fiber blend to match just about any flying insect you desire. You also have the option of blending your own individual colors for specific hatches on your local waters. They are waterproof marker (Chartpak AD Markers) friendly as well. EP™ Trigger Point Fibers have been treated with Watershed (Watershed Waterproofing Liquid) which helps your flies sit proper in the water column. ENRICO PUGLISI TRIGGER POINT INT'L FIBERS are 8” long.
