The Shimano Ocea Nylon Casting Leader is made from a combination of two advanced nylon resins, resulting in a soft yet strong leader. With moderate stretching properties and a high strength knot, this leader allows for effective saltwater casting techniques. It also boasts high transparency and good flexibility. Specifically designed for powerful fish like giant trevally, kingfish, and tuna, this premium monofilament leader has excellent stretch and abrasion resistance to prevent tackle failure. It is also the preferred choice for specialized top-water casting techniques, maintaining a solid connection and hook-set even under heavy drag settings.
