UNI-Floss is a strong, glossy, single-strand fly tying floss designed for creating smooth, vibrant bodies on trout flies, salmon flies, steelhead patterns, wet flies, soft hackles, streamers, and traditional fly designs. Made with a durable 600-denier rayon-style construction, this floss lays flat on the hook shank to help build clean, even profiles with rich color and a polished finish.
Unlike many traditional multi-strand flosses, UNI-Floss resists splitting and fraying when handled carefully, giving fly tyers better control when wrapping bodies, tags, ribs, and woven patterns. Its high sheen makes it especially useful on classic patterns where color, smoothness, and presentation matter, from bright salmon and steelhead tags to clean-bodied trout flies like the Royal Wulff.
UNI-Floss is a dependable choice when you want a clean, glossy body without fighting bulky or uneven material. It lays flat, wraps smoothly, and provides strong color payoff on both traditional and modern patterns. We especially like it for bright tags, classic wet fly bodies, salmon and steelhead flies, and woven nymph bodies where a smooth finish and vibrant color make a noticeable difference.
UNI-Floss is ideal for tying:
For the cleanest results, start with a smooth thread underbody so the floss wraps evenly and shows its full glossy finish. Keep your fingertips clean and smooth, since rough skin can snag or fray rayon-style floss. For bright or translucent colors, use a white or matching thread base to prevent darker thread from showing through.
Wrap UNI-Floss with light, steady tension and smooth touching turns to maximize sheen. When working from the spool, tying a small stop knot near the end of your pulled working length can help remind you when you are running low before finishing the fly.
