The perfect blend of the ORIGINAL EP™ FIBERS to match the hatch! When I fish I pay a lot of attention to the baitfish and their behaviors. For years I have observed baitfish do change color in many situations, especially when under attack from predators. If you want to simulate these natural color changes EP™ 3-D FIBERS will do the trick for you. Our synthetic materials are extremely durable. They will last many catches, and keep any profile silhouette. Certainly these fibers will make the difference in your patterns.
