UTC Ultra Thread 70

Ultra Thread 70:This is a great size for tying the smallest of flies and for tying with low bulk on larger flies. It is the ideal choice for dry flies, nymphs, and midges size 14 or smaller. Available in 32 colors.

Ultra Thread has been engineered as a fly tying thread from the beginning. It is not an “off the shelf” thread as are many others. All of Ultra Thread’s characteristics were carefully chosen to enhance its tying performance. Here are a few of the thread characteristics that make Ultra Thread ideal for fly tying:

• UTC chose nylon over polyester because nylon will stretch and grip materials better. This allows for more uniform tension and gives the tyer the “feel” for maximum tension. Nylon is the same strength as polyester (given the same denier) and offers the added benefit of more intense colors and a larger range of colors. Because nylon stretches, it grips material tighter and makes the fly more durablUltra Thread has been lightly waxed. This also limits thread build up and gives the thread a smoother, slicker feel. The added benefit is that head cement fully penetrates the thread which equals more durable flies.

•  Ultra Thread is a multifilament thread that is not bonded. Bonded threads are oval in shape and are stiff or coarse feeling. Bonded threads also build up fast which is a significant concern when tying small flies. Since Ultra Thread is not bonded, it is the best choice for split thread tying techniques.
