With its low visibility olive tint, Umpqua's co-polymer nylon tippet material is an almost flawless marriage of great tensile strength, elasticity, suppleness, and abrasion-resistance. The result is a tippet material of superior WET KNOT STRENGTH that remains supple enough to allow a fly to really "swim". Matches perfectly with our Trout, Power Taper, and Bass/Panfish leaders.
