The RIO Premier (Technical) Euro Nymph Line redefines Euro-nymph fly lines: an ultra-thin floating line built on a stiff monofilament core for lightning-fast hook sets and exceptional feel. Featuring a 14‑foot .013″ pink leader seamlessly integrated into the taper, it eliminates knots and reduces fouling like no other line. The fully level taper allows anglers to cut and customize the line for any situation. Approved for competition and trusted by guides, this line delivers elite performance for serious nymphing anglers.
