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 fibre that is leaps and bounds stronger than any other fibre material on the market. For example, according to Toyobo Industrial Materials (the maker of 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 fibres that includes Kevlar (aka the stuff bulletproof vests are made of), among others. Available in 150 and 300 yard spools in test strengths ranging for 2.7kg to 2.7kg.
