New for Fall 2026! We are proud to introduce the Rio Ambassador Series Oliver White Flats Passport Fly Line. We know Oliver, and Oliver knows the salt! We can assure you that this line will be a staple on MRO Saltwater trips moving forward.
Transcontinental flats fishing is a game of calculated chance. It takes a willingness to roll with whatever the day gives you- tides, variable conditions and split-second decisions. A deep knowledge of intended targets- from permit to tarpon to bones and beyond. And of course, it calls for a smart fly line with the ability to push limits and the wherewithal to make the shots, no matter the circumstances. Enter the new Ambassador Series Flats Passport, a far-ranging tropical floating taper designed for worldwide flats exploration- and made in collaboration with globetrotting angler, Oliver White.
* Front loaded head loads rods quickly and effectively for short casts
* Short front taper supplies the power to turn over long leaders and heavy flies into stiff breezes
* Extra long head (58′ for WF8F) and extended rear taper enables anglers to carry or pick up long lengths of line for precise shots to distant fish
* 1/2 size heavy
Technology and Features:
* Slick Cast- designed to outcast and outlast! Some of the slickest, most durable lines made
* DirectCore- is Rio’s highest performing, tropical conditions core, and perfect for hot, humid climes. Lines built with DirectCore have the stiffness to resist becoming limp spaghetti out on the flats, or in the jungle, yet have no memory and are easy to straighten – ensuring your fly lines lie completely straight on the water
* EasyID- never guess again
* Front and back welded loops
* SureFire- Rio’s exclusive, triple color marking system. Improves casting accuracy by making it easy to gauge exact distances with a quick glance.
“I want a tool that lets me do what I want to do. In this case, I needed to be able to throw a long leader because I think it matters. And I also wanted to be able to aerialize and cast more line…..to be able to pick up and reposition it precisely, without having to strip in a short head. This line effectively executes the action I’m interested in creating…one that’ll enhance your overall experience on the flats.”- Oliver White/Rio Ambassador
