Spiderwire Braided Stealth Superline delivers smooth and quiet performance to give you the upper hand. Made with Dyneema ultra-high molecular weight polyethylene fibers. These strong, smooth, and round fluoropolymer-treated microfibers allow Stealth Superline to cast farther. The no-stretch properties of Dyneema fibers also offer exceptional sensitivity to instantly detect bites and help prevent the line from digging in on reels. Superline is now packaged in a thinner spool designed to take up less weight and less space in your tackle box.
