The Copper John nymph carries a classic mayfly/stonefly profile. A sleek abdomen reflects light creating the illusion of movement as well as adds weight to the nymph, helping it sink for deeper water. This pattern is great in any river where there are large populations of mayflies and stoneflies. Per 3. Sizes: 12, 14, 16, 18, 20. Color: Chartreuse.
