It doesn't get much more classic than a natural Hare's Ear. This fly will get you to depth with its gold brass bead. The bushy olive body and wing case built over the bead are all features that make this classic fly deadly!
The Hare's Ear nymph is a great general pattern with the addition of a heavy brass bead to help get down, it catches a huge amount of fish all over the world on both still and running water. Barbless.
