Ocea 8 represents the pinnacle of Shimano’s braided line engineering, expertly manufactured in Japan to match the performance demands of flagship reels like the Stella SW and Ocea Jigger. Built with advanced 8-carrier construction and incorporating cutting-edge technologies including TOUGH CROSS 2, HEAT SINK COATING, and FILAMENT X, Ocea 8 delivers exceptional abrasion resistance, heat control, and linear strength. This premium braid is purpose-built for offshore and heavy-duty fishing applications where reliability is non-negotiable.
If you’re a serious offshore angler using heavy-duty spinning or multiplier reels, a high-quality braided line is essential for maximising both performance and enjoyment - and Shimano’s Ocea 8 is built to deliver exactly that. Crafted in Japan, Ocea 8 features exclusive Shimano technologies that offer unmatched reliability in demanding environments. TOUGH CROSS 2, a 45-degree tensioned weave, significantly boosts abrasion resistance - ideal when fishing near reefs, wrecks, or rugged structure. The HEAT SINK COATING, a low-conductivity silicone layer, minimises frictional heat at the rod guides, helping prevent guide damage during long, high-pressure fights. Meanwhile, FILAMENT X, an exclusive Izanas fibre lay-up, enhances both linear strength and wear resistance for confidence in every hook set and retrieve.
Engineered for advanced techniques like offshore jigging and long-range casting, Ocea 8 delivers exceptional strength, ultra-high sensitivity, and long-lasting durability. Whether you're working large poppers or deep-jigging in strong currents, Ocea 8 allows you to fish harder, smarter, and more efficiently - especially in extreme conditions where gear failure is not an option.

Manufactured in Japan, Ocea 8 features an advanced 8-strand construction, tightly woven using Shimano’s TOUGH CROSS 2 technique - a 45-degree tensioned braiding process that dramatically enhances abrasion resistance. It’s further equipped with HEAT SINK COATING, a silicone-based treatment with low thermal conductivity that reduces frictional heat at the rod guides, especially critical during long fights under pressure. At the core of Ocea 8 lies FILAMENT X, an exclusive lay pattern of Izanas fibres developed for Shimano to optimise linear strength and further increase resistance to wear. Ideal for pairing with the Stella SW, Ocea Jigger, and other heavy-duty spinning or multiplier reels, Ocea 8 offers the strength, sensitivity, and reliability demanded by modern big-game anglers. Available in 400m spools to meet the demands of inshore and offshore anglers.
