Raven Invisible Fluorocarbon Leader Line

RAVEN Invisible is made of 100% fluorocarbon material.  The 30m (33yd) spool is available in four strengths.

Invisible - Has a refractive index (the degree to which light bends as it passes through a substance) that is nearly identical to the refractive index of water, making it virtually invisible when immersed in water.

Hydrophobic - Does not absorb water, so it won't weaken or increase in stretch when wet, unlike nylon fishing line. 

High Density - makes it sink faster than nylon lines, allowing the bait to run more naturally along the bottom.

Low Stretch - less stretch than nylon, particularly when wet, allowing for crisper hook sets.

Strong and Durable - superior abrasion resistance, tensile and knot strength.
