RIO SlickCast.

The smoothest, most durable coating on the market. Produces the least friction ever measured on a fly line. What does SlickCast do for you?

Fly line travels through the guides at higher speeds for longer casts.
The ultra-slick coating also allows anglers to fish more efficiently as the line slides through the guides with less friction for longer, drag-free drifts.
In addition, SlickCast continuously releases essential anti-stick agents that migrate to the surface of the line.
This ensures a line that remains as smooth as the day it was made, giving anglers many years of high performance and distance.
When it comes to durability, SlickCast's proprietary formulation produces the toughest, most durable coating in the world.
Lab tests show that a line constructed with SlickCast lasts 140% longer than our closest competitor and in abrasion and cracking tests, lasts 33% longer.
