RIO’S Steelhead/Salmon Leaders are built to match the needs of the steelhead and salmon fly fisher. The leaders are made of a medium stiff nylon that is incredibly tough and highly abrasion resistant, and designed with a powerful taper design that easily turns over larger flies, and cope with tough winds. It is ideal for all Spey rods and lines, as well as for the single handed steelhead and salmon fly fisher.
