Ultra Thread 210 is a versatile saltwater fly-tying thread. It has the perfect amount of stretch to help tension down on your materials to help make for more durable flies. The Ultra Thread 210 wraps smooth, doesn't fray easily, and lays flat. As a result, it is becoming increasingly popular for saltwater flies. For example, its equivalent diameter in Danville is 6/0, a size most often used with trout flies. So you get a thin diameter with a breaking strength of around 2 pounds. Ultra Thread was designed for fly tying and isn't just a re-purposed thread from some other application. Our Pro Flat 70d thread is the perfect choice for tyers who want the thread to lie flat. We use this thread forlarge streamers and saltwater patterns where you need a lot of binding strength. One of its key attributes is its great binding strength making it easy to grip materials and hold them securely in place.
