This is a little bit of red with a transparent UV that has extreme glow.
Simply put, this is the hottest UV material I have ever come across. If you do not have the " RED UV Fly" your not catching the amount of fish you should!! This fly is a great shallow running fly when ran off planer boards or down deep on a rigger. Rigged with #4 treble hook, 6 clear glow beads on 20lb leader.
