McFlylon Black — Hareline Floating Wavy Polypropylene Yarn

McFlylon Black: Bright, buoyant, and versatile yarn for fly tying

Hareline McFlylon Black is a bright, wavy polypropylene yarn designed for fly patterns that require lightness and buoyancy. The material floats on the water and catches the light with a subtle gloss, helping your patterns stand out in both shimmering currents and calm surface water alike. The product stands out not only for its buoyancy but also for its broader color options compared with standard spooled polypro, making it easier to match hatch colors and water conditions without sacrificing performance.

Designed for multipurpose use, McFlylon combines a delicate texture with dependable buoyancy. The lightweight strands reduce bulk while increasing the visual footprint of your fly, enabling better visibility and movement on the water. Its quality construction supports repeated use across many tying sessions, so you can experiment with different patterns and placements without compromising performance.
