Step up to the ultimate in braided-line performance with Berkleys x9 Braid Fishing Line. Made of 100% polyethylene fibers, x9 Braid combines nine strands of material into a super-compact, round, tightly-woven line. As a result, x9 Braid is significantly stronger and smoother-casting than other premium polyethylene lines that use eight-strand technology. Berkley x9 Braid provides maximum casting distance with minimum noise in the guides, in addition to its near-zero stretch sensitivity. Color: Pearl White.
