Sufix Nanoline Nylon was developed for trout fishing using the lightest mini-spoon lures. The limited flexibility of the Sufix Nanoline line makes it very sensitive and allows you to feel the slightest bites. It enables quick hooking, is effective, and reduces the number of lost fish. Sufix Nanoline has greater frost resistance. It is suitable for fishing at sub-zero temperatures, as it does not lose softness and flexibility. This is a great advantage when fishing early in the season or in mountain streams.
