Veevus GSP Thread (Gel Spun Polyethylene) is an ultra-strong, super-thin tying thread designed for the most demanding fly patterns. GSP is many times stronger than standard polyester or nylon threads of the same diameter, allowing tiers to apply maximum pressure without risk of breakage. Naturally slick, it slides smoothly through materials yet bites well when finished with proper thread wraps or knots. For large, bulky, or material-heavy flies, Veevus GSP is unmatched in strength and reliability.
