An excellent substitute for floss when creating tags, butts, and bodies on salmon and steelhead wets, Uni-Stretch Nylon's spongy elasticity allows fly tiers greater control and coverage. 100% synthetic and uniquely color-true when wet, Uni-Stretch has proven a favorite for shaping robust underbodies on many trout nymphs, streamers, and plump dry flies like Humpies and Trudes too. Available in a wide array of vivid colors certain please, give Uni-Stretch Nylon a try! (Single-ply, non-waxed, 30 yards per spool)
