The RIO Flats Passport - Ambassador Series Fly Line is a tropical floating fly line designed for anglers who need powerful, precise presentations across worldwide flats fisheries. Created as part of RIO’s Ambassador Series in collaboration with Oliver White, this line is built for permit, tarpon, bonefish, and other demanding saltwater targets.
The Flats Passport features an extra-long head and extended rear taper that allow anglers to carry more line in the air, pick up longer lengths of line, and reposition casts with precision. The WF8F model features a 58-foot head, giving experienced flats anglers the ability to make controlled shots at far-ranging fish without constantly stripping back to a short head.
A half-size heavy, front-loaded design helps load rods quickly for short shots, while the short front taper provides the power needed to turn over long leaders and heavier flats flies in stiff breezes. Built with SlickCast, DirectCore, SureFire, EasyID, and front and back welded loops, the Flats Passport is ready for technical saltwater presentations.
