Iwan-E-Dun

The Iwan-E-Dun is an innovative dry fly pattern designed by Phil Iwane to replicate the adult mayfly dun with remarkable precision. This fly is particularly notable for its extended monofilament body, which captures the sleek and glossy abdomen of natural mayflies. Originally developed to fool wary and selective trout in the clear waters of Colorado's Cheeseman and Eleven Mile Canyons, the Iwan-E-Dun has become a go-to choice for anglers seeking a realistic and effective mayfly imitation.

In faster water, pair the Iwan-E-Dun with a small emerger dropper. This setup provides an enticing dual presentation for trout feeding on both surface duns and emergers just below the film.
