Shimano Ocea 17+ Hollow Core Braided Line delivers unmatched strength and casting performance in an impressively slim profile. Designed for offshore anglers, this line features a 16-strand braided sheath with a single core thread to ensure superior linear strength. Its HEAT SINK COATING, made from a specialized silicone resin, protects against friction and heat buildup during intense, drag-heavy runs. The use of IZANAS polyethylene fiber provides ultra-high strength while maintaining a low diameter, allowing for smooth casting and reliable knot strength. This line flows effortlessly through guides and off the spool, offering enhanced sensitivity and durability for demanding saltwater conditions.
