Description Berkley’s Trilene Z Monofilament Line is a high-performance monofilament line made possible with Berkley’s advanced “crystalline” manufacturing process. Made in Japan, this line offers high sensitivity, ultra-low stretch, and high strength bringing this line closer to the performance of fluorocarbon than most other nylon lines. It’s low-stretch and highest in class strength, in both linear and binding strength, allows for it’s high sensitivity allowing you to “feel” what is going on under the water with your lure and to detect delicate bites. This line is also ultra-wear resistant allowing you to take on any structure needed during the course of your fishing outing. Berkely also ensures the angler can use every inch of the line by utilizing parallel spooling which maintains the shape and integrity of the line. They have also added a halfway mark on the line at 75m, so you can conveniently spool it equally across two reels.
