What is UTC Ultra Thread 70 Denier?
UTC Ultra Thread is a lightly waxed multifilament thread that can be flattened completely while tying. This produces exceptionally smooth fly bodies with minimal bulk, making it an excellent choice for smaller hook sizes and refined fly patterns.
Because the thread is not bonded, it can easily be split for split-thread dubbing. Adhesives and head cements penetrate the fibres effectively, helping to create stronger, more durable flies.
Ideal For
- Dry flies
- Nymphs
- Emergers
- Midges
- Split-thread dubbing
- Slim, realistic fly bodies
