This synthetic chenille fly tying material combines a gel core with mobile flex UV fibers, locking strands firmly in place while adding a subtle ultraviolet sparkle that increases visibility below the surface. The gel core prevents fiber loss during tying, so you can wrap dense, even bodies on leeches, blobs, and attractor patterns without splitting or fraying. Dyed to the core using a computer-controlled process, each strand maintains consistent, vibrant color throughout, giving tiers confidence when building high-contrast patterns for pressured fish. An array of unique colors makes it easy to match water clarity, light conditions, and seasonal forage while keeping flies durable through repeated casts and aggressive strikes.
