Textreme Brill Card 5 mm is a must-have tying material for demanding fly tyers. Composed of a very fine core and entirely transparent fibers, it creates translucent, natural-looking bodies that are particularly effective on nymphs and drowned flies. Combined with a CDC thorax or soft hackle collars, it increases attractiveness and imitation tenfold, making it a formidable choice to seduce even the most wary fish. Packaged in 3-metre cards, this 5 mm Brill offers both versatility and practicality, and is also available in a spool version to meet the different needs of riggers.
