Description: Spooled Antron yarn is super-convenient to store and use. The most obvious purpose for it would be as a shuck on a Sparkle Dun or X Caddis dry fly but it can make a great nymph or wet fly thorax with picked-out legs or even a full-length body (looks great with a rib). However you use it that trilobal reflection will ring the dinner bell for the trout.
