Sunline SX1 Braid is a re-designed and upgrade version of the super popular Japanese Sunline PE braid.  Sunline asked Aaron Martens and Brent Ehrler to help them design the ultimate finesse braid, and the result was SX1.  The new SX1 Braid utilizes the same suppleness that made the PE braid famous, but adds extra durability to extend life and resist breakage.  Sunline SX1 Braid is the new standard of 4 strand finesse braids, and sure to become your favorite spinning reel braid.
