Super-durable and sensitive, Strens Braid Superline is crafted of Dyneema, known to be The Worlds Strongest Fiber. The tightly woven polyethylene fibers feature a Glide Coat surface treatment, resulting in a slick finish that slides easily through the rod guides; with its perfectly round profile, Stren Braid Superline casts extremely well and resists digging on the spool when retrieved under load. The outstanding knot strength, small diameter and high strength make this line ideal for many applications. The Clear/Blue Fluorescent color has the advantage of glowing under a black light, for excellent nighttime visibility.Made in USA. Cancer and Reproductive Harm- www.P65Warnings.ca.gov.
