FAQ

Cleaning your fly line is very important especially when fishing saltwater. Simply pull line off your reel into a clean bucket or tub of freshwater. Put roughly 1oz or more of Cortland’s Line Cleaner solution onto a clean rag or towel. Firmly squeeze the towel with Pro Line Cleaner around the line and slowly pull line through the towel. You should be able to see dirt or discolored streaks on the towel when finished.

Classics never die.

Used this on 10’10” 6wt Euro rods to make them versatile for steel Head fishing. They cast beautifully.

Go-To Fly Line

I have used Cortland Classic 444 SL for 2 decades. When I try some other brand, I come back to this one. It loads easy and shoots off the rod like it is rocket propelled. It works with either the tiniest dry fly and a number 6 bass popper in dead calm or a Montana wind storm. Clean it every two or three days with the Cortland line cleaner and you will not be disappointed.
