MADE FROM PREMIUM copolymer, our Synchro Dynamic System (SDS) Tapered 13 Dry Fly Leaders are designed to synchronise energy transfer from the fly line to the fly with seamless proficiency. Our tapered leaders retain maximum knot strength per weight class and benefit from a low refractive index when submerged in water. With an optimised taper configuration, each of our abrasion- resistant leaders ensures perfect fly turnover cast after cast. Low refractive index High tensile strength High abrasion resistance Hand tied loop at butt
