UTC 140 Ultra Thread is a step-up in durability and thickness from its classic line of 70-denier threads. The 140 denier Ultra Thread is the standard for tying big bugs, including hopper patterns, streamers and mice. If you’re tying bigger flies, you’ll want the additional thickness and strength that UTC 140 Ultra Thread provides.
