Uni-Cord 12/0 Gsp Thread is a compact, high-strength fly tying thread designed for precise wraps under demanding conditions. With 50-denier construction and a four-pound breaking strength, it handles the toughest jobs in the vise.

This fishing thread shines in trout fly work: it excels at deer hair spinning for trout flies, and it holds together large foam flies under pressure. When dubbed with the split-thread method, it builds almost indestructible bodies that resist compression and fraying during tough casts and fish strikes.

The fiber remains stable in varied conditions, giving clean, consistent wraps whether tying slick deer hair or bulky foam bodies.
