The chilly conditions of the late season can reduce the effectiveness of standard fishing line. Berkley Trilene Cold Weather Monofilament Line is specially formulated to retain its soft, supple character in low air and water temperatures. So rather than that heavy, sluggish feeling that leads to frequent twists and tangles, Trilene Cold Weather Mono provides super flexibility and responsiveness, with low memory. Casts well; great for ice fishing, especially out in the open. Made in USA. Test available: 2 lb., 4 lb., 6 lb. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Ice Fishing Line.
