The perfect blend of EP™ FIBERS to match the hatch! When I fish I pay a lot of attention to the baitfish and their behaviors. I have observed that they change color in many situations, especially when their predators attack them. If you want to simulate these naturals color changes EP™ FIBERS 3D will do the trick for you. Certainly these fibers will make the difference in your patterns. EP™ 3-D FIBERS are 10” long.
