Umpqua's Tough Nylon tippet material is a stiffer, harder material that is very abrasion resistant and better at turning over larger flies. It is perfect for salmon and steelhead fishing with sink-tips where abrasion resistance is more important, the flies are larger, and tippet diameter is not as important. Recommended for Umpqua's Shorty, Bass, and Steelhead/Salmon leaders. 30 yards per spool. Olive tinted.
