This premium line consists of a copolymer core and a fluorocarbon coating and is P-line's most versatile line. The fluorescent tint to the line gives it excellent visibility under a black light when night fishing. Yet, in the daylight, the fluorocarbon component makes the line nearly invisible in the water. This line has an incredibly low stretch, giving it exceptional sensitivity. The fluorocarbon coating also prevents the line from absorbing water, improving castability and overall performance. 4 lb. test on a 300 yard spool.
