Nano Silk is widely regarded as the professional fly tyer’s thread of choice and one of the finest GSP (Gel Spun Polyethylene) threads available. Renowned for its exceptional strength-to-diameter ratio, it offers unmatched performance for everything from the smallest micro flies to larger, demanding patterns.

Nano Silk Ultra lays perfectly flat on the hook, eliminating unwanted thread build-up, even with multiple wraps. In fact, extensive testing shows that even after 100 wraps, head build-up remains virtually non-existent. The thread can also be split further if required, making dubbing loops exceptionally easy to form.

Manufactured using the highest quality GSP materials, Nano Silk Ultra offers smooth handling, consistent performance, and superb reliability.
