This is a speciality “Hand Made Blend,” of natural fur and synthetic fibers especially designed for Czech, and Euro style nymphs but its uses go well beyond it’s name. C.N.D. is a one of a kind product consisting of superfine trilobal and pearlescent fibers mixed with natural camel and rabbit hair. This is what we like to call a pro-blend, the reason it’s called a pro-blend is simply because these types of complex hand blended dubs. were only available to professional fisherman that had access to speciality blends or were willing to mix it themselves. Hemingway’s saw the great benefits and extreme fish catching ability of this wonderful product and decided to unlock this secret and offer it to fisherman all over the world!
