At 100 denier (comparable to 6\/0), it offers an exceptional strength-to-size ratio, boasting a breaking strength of approximately 13 lb (6 kg) in a flat, low-profile format. This color-stable, dope‑dyed thread resists UV fade and color bleeding, ensuring your wraps maintain their color in harsh, saltwater environments. With 109 yards (100 m) per spool and a smooth laydown--simply twist the thread to get a rounder profile--it’s designed to deliver professional-level performance and reliability..\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUses\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNano Silk Saltwater Thread excels when building secure, neat bodies and thread heads on saltwater streamers, predator patterns, and deer-hair-spun heads. Its flat profile prevents bulk accumulation and allows clean no matter what fly you're whipping up. Dope-dyed integrity also means you won’t have to worry about your thread’s color bleeding into epoxy or UV finish, making it ideal for those foot-long flies that you keep in the box for years and only bring out on the special occasions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComparisons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCompared to a similarly rated 6\/0 polyester thread, like 6\/0 UNI-Thread, the Nano Silk Saltwater 100D stands out for its exceptional GSP strength and durability. While UNI-Thread provides reliable performance, the Nano Silk’s gel-spun construction offers notably higher tensile strength (around 13 lb vs. approximately 4–5 lb for polyester 6\/0) and resists rot or UV degradation due to its excellent durability. If you're tying large saltwater or predator flies and want a thread that holds tight without fraying, color fading, or breaking under pressure, Nano Silk Saltwater is one of the best options out there.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Semperfli","offers":[{"title":"Black","offer_id":48478225924329,"sku":"SKU886741012072","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Blue","offer_id":48478225957097,"sku":"SKU886741012089","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Dark Gray","offer_id":48478225989865,"sku":"SKU886741012102","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Dark Green","offer_id":48478226022633,"sku":"SKU886741012096","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Orange","offer_id":48478226055401,"sku":"SKU886741012133","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Pink","offer_id":48478226088169,"sku":"SKU886741012188","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":48478226120937,"sku":"SKU886741012157","price":4.95,"currency_code":"USD","in_stock":true},{"title":"Rhyac Green","offer_id":48478226153705,"sku":"SKU886741012119","price":4.95,"currency_code":"USD","in_stock":true},{"title":"White","offer_id":48478226186473,"sku":"SKU886741012164","price":4.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/1846\/1673\/files\/semperfli-fly-tying-semperfli-nano-silk-saltwater-100d-thread-1199955784.jpg?v=1761895817","url":"https:\/\/www.tridentflyfishing.com\/products\/semperfli-nano-silk-saltwater-100d-thread","provider":"Trident Fly Fishing","version":"1.0","type":"link"}
