Easy casting all-around trout line, with low- stretch, ultra-slick performance.

Elite RIO Perception


The Elite RIO Perception is an easy casting, general purpose fly line that casts nymphs, dry flies, streamers and soft hackles with ease. The short head makes this a particularly good line on smaller rivers and lakes when long distance line control is not necessary. 

This line is built with RIO's low-stretch ConnectCore Plus, resulting in exceptionally smooth, durable fly lines, with the added benefits of incredible levels of sensitivity when casting and fishing, and providing enhanced detection of takes, faster hook sets, and far greater control when playing a fish. In addition, this line is built with SlickCast, RIO's proprietary coating technology, creating the slickest, most durable fly lines on the market. Lab tests show that lines built with SlickCast have the least amount of friction ever measured in a fly line.

The RIO Perception is the best all-around fly line on smaller rivers and lakes.
