Daiwa J-Braid X4 is a 4-ply PE braided fishing line precision-woven in Japan using premium Dyneema fibers. Its round profile and low-stretch design support smooth casting, sensitivity, and hook-setting power, while its very high abrasion resistance suits fishing around structure and heavy cover.
Choose Dark Green for a stealthier presentation when tying directly to a lure without a leader; it blends naturally into freshwater and inshore environments. Fluorescent Yellow is a high-visibility option for tracking line and spotting subtle bites, including during finesse techniques or low-light conditions.
The listed 300-yard options are available in both colors at 20, 30, 40, 50, 65, and 80 lb. The supplied 150-yard model specifications are:
