The standard tying thread used by most fly tyers for hook sizes #6 to #10. It is characterized by a particularly rough surface, which renders it suitable for tying any type of dubbing. It has excellent tensile strength in relation to its size, is suitable for tying large bodies.
Textreme Standard 3/0 Thread is a perfect choice of thread for larger trout and salmon flies and is 135dn thick. It has added strength, yet still has a fine diameter and feels much lighter than comparable threads at this thickness.
