What is Semperfli Chadwick's 477 Wool?
After the original Chadwick's No. 477 yarn disappeared from production, it became one of the most sought-after materials among traditional fly tiers. Semperfli carefully recreated this iconic wool to closely match the original colour and texture in both dry and wet conditions.

FLYFISHING.BG RECOMMENDSFor the most authentic Frank Sawyer-style Killer Bug, separate the yarn into individual plies and use a single strand on smaller hooks. This produces a slimmer body while preserving the distinctive colour and texture that made the original Chadwick's No. 477 famous among generations of fly anglers. |
