Cortland C12 Hollow-Core Super Braid Fishing Line (600 yd Spools)

Cortland C12 Blue Super Braid delivers premium hollow-core backing for offshore anglers seeking strength, line capacity and value. Manufactured in Cortland, New York, its 12-strand gel-spun polyethylene construction combines a small diameter with high break strength to maximize reel capacity. The spliceable hollow core allows anglers to create reliable end loops for wind-on leaders or direct connections to monofilament and fluorocarbon top shots.

Cortland’s proprietary FiberTech treatment penetrates the braid and bonds with individual fibers to add stiffness, improve handling and protect the line. ColorLast technology helps the blue color resist fading and bleeding, maintaining its appearance through repeated use. Together, these features make C12 a durable, manageable option for building offshore backing and leader systems.
