The ultimate, all-around floating line for TROUT with ultra-slick performance.

The RIO GOLD has a revolutionary taper design that gives incredible loop stability at distance, a unique profile that allows a rod to load at close range and a front taper that delivers perfect presentation of flies between sizes #22 and #2. The RIO Gold is the ultimate all round, floating line for the trout fly fisher and is built with "MaxFloat Tip" technology, RIO's proprietary tip coating formula that floats more than twice as high as regular line tips, without any increase in diameter. In addition, this line is built with SlickCast, creating the slickest, most durable coating on the market—producing the least amount of friction ever measured in a fly line.

Features of the Rio Gold Fly Line:

• Long head for ultimate casting control
• Built with RIO's exceptionally slick, durable SlickCast
• Front biased weight to load rods at close range
• Taper design to cast flies between #22 and #2

THE SLICKEST LINES ON THE MARKET!
Rio's SlickCast lines are the slickest lines out there on the market. You will be stunned by the slickness after countless days on the water. Notice the extra distance that comes with ease, the extended drag-free drifts, SlickCast lines slip effortlessly through rod guides. And, as essential slickening agents constantly migrate to the exterior surface, you can trust your SlickCast line to be as slick next season as the day you bought it.

PERFORMANCE & DURABILITY!
You’ll start to recognize the durability on Day 25, you’ll appreciate it on Day 50, and you’ll be blown away by it on Day 80. SlickCast’s proprietary formulation is off the charts when tested for abrasion and cracking resistance—producing the toughest, most durable fly line coating in the world. You can count on your SlickCast line to outlast every other fly line you have ever fished.

LOWEST FRICTION!
Fly line slickness is the most important factor for getting distance and for feeding slack on drifts. Simply, the slicker a line is, the more effective and efficient you will fish due to easier distance and extended drag-free drifts.

TESTING METHOD – To test the fly line slickness, Rio weaves a sample through a series of chrome bars. One end is tied to a weight, and they pull the other end to start the line moving and maintain its motion. They measure the force it takes to start the line moving, as well as the force required to maintain motion. The higher the forces required the more friction the line has—not good for long casts and shooting line.

33% MORE FISHING TIME BEFORE CRACKING THAN THE NEXT BEST TECHNOLOGY
Fly lines crack over time and use. The more durable a fly line coating is, the longer a fly line will last before it cracks, and the more fishing time you get out of a line.

TESTING METHOD – Rio replicates the conditions that cause a fly line to crack (usage) by attaching a weight on one end of the line and pulling the fly line back and forth continuously through their lab version of a rod tip top, and recording the number of cycles it takes until seeing the first sign of cracking.

140% TOUGHER COATING THAN THE NEXT BEST TECHNOLOGY
As fly lines get used, the action of the line moving through rod guides gradually wears off (abrades) the surface of the coating. As abrasion appears on the coating, the line gets rougher and doesn’t shoot or float as well. The longer a line lasts before abrasion, the higher the line’s performance.

TESTING METHOD – To test abrasion resistance, Rio attaches a weight to one end of the line, drapes it over a chrome bar, and cycles it back and forth over the bar, rubbing the same section of coating until it starts to abrade.
