Troutline Tactical CDC Dun No.4 is a highly effective olive dun pattern tied with a delicate CDC wing. Designed for super-selective fish, this fly excels in slow-moving river sections where trout and grayling carefully inspect every insect drifting on the surface film.
We tie these flies slim and delicate, with realistic thread segmentation that perfectly imitates natural insects. Crafted with premium CDC feathers and the finest Japanese barbless hooks, each fly offers durability, balance, and secure hook-ups.
A proven pattern for large, wary fish, the CDC Dun No.4 is a must-have addition to every angler’s fly box.
