The Super UV G-Core 15 mm has been designed for creating stillwater flies, with a special mix of fibers that simulate movement even when the fly is used for static fishing without retrieval. The addition of ultraviolet fibers increases the attractiveness of the entire color range, giving a purple/blue hue, especially to darker shades. The thermofusible bonding core, made with cutting-edge materials, is very thin yet robust, and it holds the effect fibers perfectly. This allows for tying on small hooks or creating bicolor or tricolor effects, even in combination with other chenilles, as it does not thicken the body of the fly. - 2-meter package - 15 mm. fibers
