UTC Ultra Thread 70 Denier - 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.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.
