The ultimate new braid in the J-Braid family, Daiwa J-Braid Grand x8 is some of the strongest and most abrasion-resistant 8-carrier braided fishing line ever put on the market. Yet, despite its durability, J-Braid Grand x8 is also extremely soft, supple, and easy-to-spool.

How is fishing line with such remarkable characteristics possible? J-Braid Grand x8 is spun with IZANAS, a new, state-of-the-art, high-modulus fiber that is leaps and bounds stronger than any other fiber material on the market. Now, you may be asking yourself: "Hey, doesn't every fishing line claim to be the strongest, most supple line out there? How is this stuff any different?" And you wouldn't be wrong for wondering. Many a fishing line company has made such a claim with little, if any, evidence to support it. But the fine folks at Daiwa don't play like that: when they make a claim, they stick by it and back it up. And that's why in the graph below you can see that, when compared with other fiber materials on the market, nothing exhibits a high strength index quite like IZANAS.

It's roughly four times stronger than polyester nylon (what most monofilament is made of), twice as strong as fluorocarbon, and is even stronger than aramid, a class of military- and aerospace-grade fibers that includes Kevlar (aka the stuff bulletproof vests are made of), among others.

Gray Light J-Braid Grand x8 is a light gray color that's visible in low light, but easily blends into the water color spectrum once submerged. Available in 150 and 300 yard spools in test strengths ranging from 6 pound to 80 pound. See table below for full details on test strength and line diameter.
