This fiber is a blend of EP™ GAMECHANGE FIBERS colors, with just the right amount of EP™ SPARKLE added to give it a UV reflective property. They can be described as similar to YAK hair in texture, feel, translucency, movement and the ability not to absorb water, but with incredible durability. The fiber diameter is a touch thicker than original EP™ FIBERS, and is constructed with large crimp to achieve a more natural movement in the water. They are ideal for any large profile fly, perfectly keeping any shape you create. I am very confident EP™ GAMECHANGE FIBERS BLEND will truly change the game.
