Designed to give you an invisible presence in low water clarity conditions, Daiwa J-Fluoro Samurai Hidden Concept Fluorocarbon Line ensures a stealthy presentation in environments where clear lines tend to struggle. J-Fluoro Samurai Hidden Concept is constructed with a unique color blending technology that takes imperceptibility to a new level, virtually eliminating its presence in less than ideal water conditions. Its special green and brown camouflage tint helps it to blend in when fishing grass, muddy bottoms, and murky water. Hidden Concept is complete with all the great features of the original J-Fluoro Samurai, including a narrow diameter for maximum casting distance and sensitivity, low-stretch, superior abrasion resistance, and minimal memory.
