UTC Ultra Thread 140D

UTC Ultra Thread 140D was engineered specifically for fly tying from the ground up — not an off-the-shelf thread adapted for the bench. Every characteristic, including the spool design, was carefully chosen to enhance tying performance. At 140 denier, it's the go-to choice for larger flies, heavy dubbing applications and spinning deer hair where strength and control matter most.
