Semperfli is famous for its Nano Silk with its strongest per denier, ultra strong fibers and more material per spool than other manufacturers. Constantly innovating, Semperfli developed a version of Nano Silk with deeper, dope dyed* GSP. For this special dying technique, Semperfli introduces the colored plastic into the raw GSP as it is dyed and extruded. The result is Nano Silk Streamer 200D, an enhanced version of Nano Silk with super deep colors that will never lighten, or color run. This dope dyed GSP formula is unique in the fly tying industry. Nano Silk Streamer 200D is perfect for streamer and predator patterns with its flat profile ideal for chironomids, traditional flies and ribbing. Finer than many polyester 6/0 threads it is extremely strong, much stronger than polyester or rayon threads. Nano Silk Streamer 200D is thread that will not break easily giving confidence for the fly tyer but can be flattened completely. Check out the stunning range of no run, dope dyed colors! 100m, 109 yds per spool.
