Cortland Micron is the standard by which all fly line backing has been judged for more than 50 years. World famous for its tight, round braid, smooth low-friction finish and stretch-resistant performance, Micron is manufactured from premium Dacron fibers. Unlike looser, flat braids, Micron comes with zero twist, is virtually tangle-free and knots perfectly every time. Ask any fly angler who sees their backing more than most, and they’ll tell you they use Micron — every time.
For over 100 years
Cortland Line has been designing and manufacturing the world’s most innovative fly line and braided fishing line.
With passion and experience, we remain focused on one thing: fishing. Fishing has been and always will be what drives us to develop the most advanced lines offered today. Located in Cortland, NY – all of our lines are made in the USA. All of our lines share the latest in line technology – many technologies that Cortland itself pioneered for the industry. We hope to see you on the water. Or, better yet, stop by and see us – we’d love to talk fishing.
