What It Is
A thin, 400-denier fly tying floss for clean, smooth bodies and bright segments. Fine enough for small trout flies, and doubled over it builds bulk fast for bigger patterns.
Why It Matters
Thicker floss gets lumpy on small hooks. This one lays flat and wraps tight, so you can build a slim, even body without the bumps—or stack wraps when you want more.
How It Fishes
Use it for segmented bodies, hot spots, and the bright accent wraps that make attractor patterns pop—like the red band on a Royal Flush. A thin coat of UV resin over the top turns it into a durable, glossy body.
