Copper John

The Copper John is one of the most proven nymph patterns in fly fishing — and for good reason. Heavy enough to sink fast, flashy enough to trigger strikes, and durable enough to outlast a full day on the water. This version is tied on a Firehole 633 barbless hook, making it fish-friendly and easy to release without sacrificing hook-up rates.

The standout feature is the resin-coated wingcase, which locks in the flash and gives the pattern a hard, lacquered finish that holds up cast after cast. That pop of light off the wingcase mimics the air bubble of an emerging insect — exactly what a feeding trout is looking for.
