Fluorocarbon that cuts into the stream.
Go one step deeper.
The specific gravity of water is 1.00 and that of fluorocarbon is 1.78.
This is the highest specific gravity compared to nylon(1.14) and polyester(1.38).
This high specific gravity makes it easy to attack deeper points and deliver the bait to fish in the shadows of current drops and rocky areas without any discomfort.
We use fluorocarbon material that has both moderate stiffness and flexibility among our fluorocarbon materials.
'Jun Keiryu Fluoro" has a refractive index close to that of water and is highly stealthy, making it an ideal line for catching fish that are highly cautious.

Commitment to spooling
Spooling applying a strong load may cause curling problems when the line comes out of the spool.
'Jun Keiryu Fluoro" is made with "Non-Stress Spooling (NSS)" to ensure that the original performance of the line is not damaged.
The line color is clear so that it does not give unnecessary discomfort to creek fish.
