UNI Big Fly Thread

UNI Big Fly Thread Heavy-duty tying thread for streamers and large predator flies.

The UNI Big Fly Thread is built for strength, durability, and control when tying large patterns that demand extra holding power. With its thick, tough construction, this thread is perfect for securing bulky materials like bucktail, deer hair, and synthetics on big streamers, saltwater flies, musky, and pike patterns. Despite its strength, it lays flat and wraps smoothly, helping create durable, professional-looking flies that hold up to aggressive fish. Available in multiple colours, UNI Big Fly Thread is a trusted choice for tiers targeting big water and big fish.
