Avid Trout WF

Pale Yellow

RIO’s Avid series of fly lines were developed for the keen fly fisher with tapers and technology that enhance the fly fishing experience. The lines are designed for easy casting performance, with slightly heavier and shorter head lengths. Each line is built on a supple memory-free core, and has a super slick coating for easy distance. A welded loop on the front end allows anglers to rig easily.

AgentX is a dual layered fly line that utilizes a high floating inner coating made with more buoyant microspheres covered by a tough outer coating for maximum durability.

Extreme Slickness

Extreme Slickness technology is a chemistry formulation that results in an ultra- slick line with dirt-repelling properties.


Front Welded Loop

A neat, bulletproof loop welded at the front of the fly line for fast Spey-specific rigging.
