The Driffield Dun Barbless is a brilliant, dry fly for adult upwinged olives associated with chalkstream and northern river fishing. Its dun profile presents an upright adult at the surface for trout and grayling feeding during a hatch.
Fish it upstream with a drag-free drift. Match its size and shade to the naturals and concentrate on glides and feeding lanes. An excellent fish catcher - few moments beat watching a trout lift and take it cleanly.
