Durable 30 m multifilament nylon line designed for fly fishing on streams, rivers and lakes. Key benefits - Purpose-built for fly fishing: engineered to perform in the short, precise casts and delicate presentations required for stream, river and lake fly work. - Long, ready-to-use length: 30 meters gives you enough line for extended sessions and varied casting distances without frequent re-spooling. - Built for durability: high-strength multifilament nylon resists abrasion and repeated casting, so it lasts through multiple outings. - Flexible sizing options: available in multiple sizes to match different rod actions, tippet needs and fishing conditions. What it solves - Reduces downtime: longer length and durable construction mean fewer interruptions for replacing worn line. - Adapts to conditions: multiple size options let you choose a line that balances visibility, suppleness and strength for your water and technique. - Reliable performance: strong multifilament nylon maintains consistent handling and handling feel across casts and retrieves. Practical attributes - Function: fly fishing line suitable for use as main line, backing or specific fly-line applications depending on the size you select. - Compatibility: intended for use on streams, rivers and lakes—appropriate for wading, bank or small-boat fly setups. - Size: offered in multiple sizes to meet different fishing requirements (select the size that fits your rod, reel and target fish). - Material: high-strength multifilament nylon for abrasion resistance and long service life. - Length: 30 meters per spool/coil — long enough for routine use and flexibility in setup. Use scenarios - Mountain stream trout: Use a lighter size for delicate dry-fly presentations and precise short casts in tight pocket water. - River wading: Choose a mid-range size for greater abrasion resistance and control when casting across current or fishing deeper runs. - Lake shore or small-boat work: Select a larger size for extra pulling power and durability when casting larger flies or targeting stronger fish. Choose the size that matches your rig and water conditions. The 30 m multifilament nylon line provides a durable, adaptable solution for fly anglers who fish streams, rivers and lakes.
