SlickCast creates the slickest, most durable coating on the market, producing the least amount of friction ever measured on a fly line. Line casts through the guides with higher line speeds for unprecedented and easy
distance. The slick coating also allows anglers to fish more effectively as line slides out of the guides with less friction for extended drag-free drifts. SlickCast's proprietary formulation produces the toughest and most durable fly line coating in the world. Lab tests show that a line built with SlickCast lasts 140% longer than the nearest competitor in abrasion testing and lasts 33% longer when testing a fly line for cracking. Other features include:
SUREFIRE is RIO's exclusive, triple color marking system that improves casting accuracy by making it easy to gauge exact distances with a quick glance.
DUALTONE is a system perfected by RIO that marks the sweet spot of a fly line by providing an obvious color change in the line at the sweet spot.
FRONT & BACK WELDED LOOPS are neat, bulletproof loops welded on the end for fast rigging.
EASY ID is RIOs printed line marking system that allows anglers to quickly and easily identify each line.
