What This Thread Is

A high‑quality, lightly waxed polyester fly tying thread from Semperfli, designed specifically for trout and streamer patterns. It lays flat, grips materials well, and stays strong even in finer sizes so you can build clean, low‑bulk flies.

Best Uses

General‑purpose thread for a wide range of flies, depending on the size you choose:

Finer sizes (18/0 or 12/0): dries, emergers, midges, and nymphs
Heavier sizes (8/0 or 6/0): terrestrials and streamers

Why It Matters

Lays flat for less bulk
Slightly twisted construction lets the thread flatten on the hook shank, so you can keep bodies slim and avoid bulky heads.
Just the right amount of wax
Light wax coating adds grip on hair, dubbing, and synthetics without gumming up your bobbin.
Strong for its diameter
Built to handle tight wraps, flare deer hair, and cinch materials down without constant break‑offs.
Easy to split for dubbing loops
The construction makes it simple to open up the thread for dubbing loops when you want extra bugginess or bulk.
Wide color range
Offered in a full palette of natural, bright, and fluorescent colors so you can match hatches or build high‑vis attractors.
