Strong, Obscure, Small Trout Magnet SOS Monofilament Line is an extra-smooth copolymer line made specifically for stealth fishing in the most demanding water conditions. As such, it proves out stronger and more abrasion-resistant than other lines of similar diameter, with superior knot strength as well. You'll find that Trout Magnet SOS casts long and is easy to manage on the retrieve; the soft, neutral color fades into the background in most lake and stream environments. Perfect for your tiniest panfish and trout lures!
