Rio Premier Dog Days Gold Fly Line # 4

The Rio Dog Days Gold is the ultimate fly line for fishing in extreme heat. Designed with a hard coating and medium-stiff core, it resists softening and maintains its performance under high temperatures. The long head provides superior casting control, and the front-biased taper ensures quick rod loading for short, precise casts. Suitable for flies between #22 and #2, it’s enhanced with Rio’s SlickCast coating for long-lasting durability and smooth shooting. Ideal for summer trout streams, ponds, or baking drift boats, it handles the heat so you can focus on the fish.
