There are dozens of brands of fly-tying thread on the market, but UTC Ultra Thread has remained the preferred choice for both amateur and professional fly tiers for years.
The reason lies not only in the brand’s popularity but also in a number of practical advantages that are evident from the very first wraps. UTC uses high-quality continuous polyester filaments that provide excellent strength without unnecessarily increasing the diameter. This allows for a secure hold on materials such as deer hair, feathers, wire, and synthetic fibers, without the risk of the thread breaking easily.
One of the biggest differences compared to many other threads is that UTC can be easily controlled by rotating the spool. As the thread unravels, it becomes flat and wide, which allows for the construction of smooth and even bodies, a smaller fly head volume, and better distribution of dubbing. When twisted, the thread becomes more compact and stronger, which is especially useful for securing heavier materials. In practice, you get two different ways of working with the same thread.
UTC offers a wide range of colors—from natural olive, brown, and gray tones to bright fluorescent colors. This allows the thread to serve not only as a structural element but also as part of the fly’s design, for example when shaping segmented bodies or adding color accents.
While designations such as 6/0, 8/0, or 12/0 may vary among different manufacturers, UTC uses the Denier system, which provides a more accurate indication of the thread’s thickness. This makes it easier to choose the right size, no matter what type of fly you’re tying.
Dubbing is the material that brings the fly to life and makes it look realistic. That’s why its quality is of the utmost importance.
Wapsi’s dubbing is processed so that it winds evenly onto the thread. The material doesn’t clump and allows for excellent control over the amount you use. This is especially important for small nymphs and dry flies, where every millimeter counts.
Wapsi offers dozens of natural and UV colors that can be combined with one another. Many fly tiers mix different Wapsi dubbing colors to create completely unique shades.
Whether you prefer classic rabbit dubbing, Camel for dry flies, or modern synthetic blends with UV flash, Wapsi offers materials for nearly every fly-tying style.
If you tie flies regularly, investing in UTC Ultra Thread and Wapsi Dubbing is definitely worth it. Although they cost a little more than some budget alternatives, they offer higher quality, are easier to work with, and produce more predictable results. This saves time, reduces material waste, and results in stronger, better-looking flies.
That’s why these products are a staple in the tackle boxes of countless fly tiers around the world—from beginner enthusiasts to professionals who tie hundreds of flies every year.
