Textreme Power Thread XL 280 Denier is the most powerful thread in the range, designed for the most demanding rigs. Made from a technical polymer offering exceptional strength - up to ten times greater than steel of the same diameter - it reaches a resistance of 10 kg, making it an essential choice for very large streamers and all flies where absolute solidity is required. Its calibrated twist ensures that the line remains perfectly even yet lays flat and smooth, guaranteeing uniform underbodies and heads with no extra thickness. Ideal when you need to combine extreme strength with rapid assembly, it allows you to fill the space quickly without multiplying the number of wire turns. Available in black (stable color) and natural white (can be tinted with a permanent marker), it is packaged in 65-meter spools. As with all smooth polymer threads, we recommend securing it with a drop of cyanoacrylate at crucial stages. The use of a ceramic-tipped spool-holder is also recommended to prolong its durability. Power Thread XL is the ultimate choice for big streamer and carnivore fly tyers looking for an indestructible, reliable line.
