With braided lines, the higher the "carrier" number the tighter the weave. SpiderWire® Stealth® Smooth Braid is made with 8 carriers (the bundled poly microfibers that create the individual braid strands) and has the same diameter as other varieties in its class, so it's wound significantly tighter. This creates an incredibly compact, round core that is then coated with a thin, durable microcrystalline polymer, resulting in a smooth feel that's unprecedented in braided fishing lines, with no loss of strength, sensitivity, or toughness. Stealth Smooth casts beautifully, has zero stretch, cinches into knots with effortless precision, and features SpiderWire's exclusive Color-Lock technology, to keep your line from washing out anytime soon. The ultimate braided fishing line, Smooth is virtually as quiet and easy-flowing as mono, but with much greater feel and hook-setting power. For both casting and spinning reels. Extremely tight, 8-carrier weave Super-compact, round core Microcrystalline polymer coating Unbelievably smooth feel Outstanding strength, sensitivity, and toughness No stretch Easy knot-tying Color-Lock significantly slows color washout Smooth and quiet through the guides For both casting and spinning reels
