Semperfli Pure Silk is twisted pure silk, a staple for traditional fly patterns such as spiders or Clyde style. If you prefer a flat profile, untwist it by spinning on your bobbin holder, delivering a dual purpose material with added strength versus traditional silks. Designed to closely match historic silk colors as described in the Edmonds & Lee Brook & River Trouting reference, it provides a period accurate look with modern robustness. The denier is approximately 250d, balancing body and delicate taper for classic dries and wets.
