Textreme Standard Thread, 6/0

The standard sized tying thread used by most fly tyers. 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 uniform bodies, and can be used on #10 to #14 hooks. It lays flat and when corded, gives very little build- up.

Although rated as 6/0, it is only 110 denier so it's surprisingly fine for its high breaking strain. Lightly waxed 

– Spool of 100 meters
– Count 110 Den. – Size 6/0.
