The Sufix Nanoline monofilament is designed for fishing in commercial winter lakes. In ultra thin diameters, it is designed for ultra-light fishing techniques, in particular the Trout Area, which uses baits such as micro spoons. Its formula with very low elasticity makes it suitable for this technique where sensitivity is fundamental. The antifreeze treatment of Sufix Nanoline will allow you to fish in good conditions, without any degradation of flexibility or elasticity, even when the outside temperature drops much below zero and the wet braids actually freeze making them unusable. A real asset in the cold season.
