100 % Fluorocarbon made for fishing not the commercial grade sold by other countries. We have the only German manufactured 100 % fluorocarbon. 20 % less stretch and higher abrasion resistance compared to Mono. Very supple, which makes it easier to tie knots, no memory at all. Crystal clear even in the higher pound test, void of the "milky" appearance common with other Fluorocarbon. Higher density allowing better casting outstanding spooling for Baitcasters and spinning reels.
