RIO Fluoroflex Permit Leader

The RIO Fluoroflex Permit Leader is a top-tier, 100% fluorocarbon leader crafted for the most demanding saltwater applications. It is the ultimate tool for achieving maximum stealth and abrasion resistance when fishing clear flats for cruising or tailing permit.

RIO is a globally recognised leader in fly fishing lines and materials, with a history spanning back to 1990. The company is renowned for its commitment to innovation and for producing some of the most technically advanced and reliable lines on the market. RIO’s products are trusted by guides and anglers worldwide to deliver performance when it matters most. Crafted entirely from 100% fluorocarbon, it is extruded to exacting tolerances to ensure a knotless, flawless taper. This material has a density that allows it to sink faster than nylon equivalents, which is a key advantage when targeting fish on deeper flats. The butt section features a hand-tied perfection loop, ensuring a strong, consistent connection point for quick rigging.

The key feature of this leader is its fluorocarbon composition, which provides appreciable stealth and high abrasion resistance—crucial qualities for the harsh environment of saltwater flats. The leader is designed with a long, medium-stiff butt section that is specifically tuned to deliver typical crab and shrimp patterns with precision and control, even when casting in challenging winds. Fluorocarbon leaders also sink faster than their nylon equivalents, which is an advantage when targeting fish on deeper flats.

The RIO Fluoroflex Permit Leader is available in a 12ft (3.7m) length and a variety of breaking strains for you to choose from in our drop down menu.
