Copper John

The Copper John is one of the most productive modern nymph patterns, created by renowned fly tier John Barr. Designed for both stillwater and moving water, it sinks quickly and gets down to feeding fish fast—one of the reasons it has become a staple in trout boxes everywhere.

Its slim, wire‑wrapped body imitates a variety of aquatic insect larvae and nymphs, while the beadhead adds weight and a touch of flash. The combination of durability, profile, and movement makes the Copper John a dependable choice in a wide range of conditions, from pocket water to deep pools. A true workhorse pattern, it consistently produces when trout are feeding subsurface.
