How to Rig It

How to Present It

Lead the fly on a tight drift just faster than the bubbles, keeping near-constant contact through the seam.

Why It Works

The slim dark olive/black blend body penetrates fast water quickly while still presenting a clean natural silhouette pressured trout will eat.

History

Perdigons originated in Spain as competition flies and now define modern euro nymphing across U.S. trout rivers.
