UNI-Stretch is a nylon material that can replace floss. UNI-Stretch is easy to wrap, stays in place, and does not fray like traditional floss. It is rather thick, stretchy material that compresses and lays flat & smooth. This product is perfect material for fly gills, bodies and accents on a variety of flies. Tired of having strands of floss separate and slide down the hook end? UNI-Stretch will solve your problems. It is great for quickly building underbodies on all types of flies.
