Developed with Semperfli Ambassadors Paul Procter and Hans van Klinken specifically for fly tyers. Semperfli Classic Waxed 6/0 thread is extruded polyester with approximately 33 oz (940gm) breaking strength and is slightly more loosely twisted for a flat profile, giving more grip and less bulk than other threads. 120 (110m) yards of 150 denier thread per spool, provides incredible value to the fly tyer. Lightly waxed, easy to split. Excellent for patterns with spun deer hair, salmon and predator flies.
