The Siglon x4 line by Sunline has gained a reputation for its top-quality performance in the fishing line category. Manufactured in Japan, it has been tested by demanding anglers.

It is highly resistant to abrasions thanks to its silicon coating. The line is stiff, which facilitates the direct transfer of movement from the rod to the tip of the line. At the same time, the movements of the line's tip become more perceptible to the angler.
