Ultra Thread 140D

Ultra Thread

UTC Ultra Thread is a premium nylon fly-tying thread renowned for its exceptional strength and slim profile. Its smooth, multifilament construction allows it to lay flat on the hook shank, reducing bulk and creating clean, elegant bodies. This thread is perfect for a range of fly sizes from tiny midges to large streamers, providing excellent grip and durability for patterns that hold up cast after cast.

Available in various deniers, Ultra Thread offers tyers the flexibility to match hook size and fly style with the ideal diameter. The round, non-bonded design makes it ideal for split-thread techniques, dubbing loops, and precise material control. With a wide range of colors, it allows endless customization, catering to both subtle classics and flashy attractors.
