Black Cat S-Line Braided Line 0.55mm 300m 70kg Yellow

Black Cat S-Line — Unmatched Strength for Trophy Catfish

The Black Cat S-Line 0.55mm delivers extreme breaking strain and zero-stretch performance for demanding catfish situations. Tested by Stefan Seuß on record-class fish, this 8-strand round braid combines water-resistant construction with high-visibility yellow for confident hooksets and total control.

Incredible 70kg Breaking Strain in a Compact Diameter

The ultra-tight 8-carrier weave packs 70kg (154lbs) of breaking strain into just 0.55mm diameter. This exceptional strength-to-diameter ratio lets you spool more line, cast farther when spinning, and apply maximum pressure on powerful catfish without worrying about abrasion or knot failure. S-Line absorbs virtually no water, maintaining full strength and sensitivity session after session.

High-Visibility Yellow for Night Fishing and Line Management

The bright yellow coating makes S-Line easy to track in low light and darkness, essential for buoy fishing and detecting subtle takes. Whether you're tensioning lines at long range or managing multiple rods at night, the vivid color helps you monitor line position and respond instantly to runs.
