PRODUCT DESCRIPTION

The Proven Black Line That Deceives Stream Trout
First introduced in 2006, Kuro Keiryu has been a long-standing favorite among mountain stream anglers.
Its unique black color blends seamlessly into the shadowed currents of valley streams,
eluding detection by dramatically reducing light reflection.
This high-performance, trout-specific line has consistently delivered results,
outsmarting even the wariest fish and earning the trust of anglers for nearly two decades.

 

Cut Through Currents With High Density and Superior Abrasion Resistance
With a high specific gravity of 1.78, this fluorocarbon line delivers rigs smoothly into strike zones
—even through fast, turbulent currents.
Its exceptional abrasion resistance allows you to fish boldly around rocks and submerged wood even with finer diameters,
confidently targeting tight spots where elusive trout lie in wait.
Now available in even finer sizes: #0.15 and #0.175 (0.064mm and 0.069mm).

 

●The ultra-high-strength fluorocarbon offers a thin yet durable profile for precise presentations to cautious fish.
●High density and excellent abrasion resistance provide a tactical advantage when targeting territorial stream fish.
●A proprietary "Black" color reduces light reflection, helping to deliver your rig to the fish without raising suspicion.
●DRP coating enhances slickness and water repellency, preventing sticking to the rod.
● Non-Stress Spooling (NSS) reduces line stress and line memory.

TECHNOLOGY

  • Vivid Dyeing process

    Sunline's unique dyeing technology – vividness, visibility, and softness in one.

  • Double Resin Processing

    Enhanced performance with double layer processing In "Double Resin Processing," a double coat of various high-performance resins results in a highly competent line.

  • Non-stress spooling

    Tension-free spooling maximizes the qualities of the line. Because no stress is placed on the line as it is spooled, the line comes off ready to deliver superior stretch performance.
