The Cortland 333 Name has been an integral part of fly fishing around the world for more than 50 years. First introduced in 1953 as the 333X, with the X meaning experimental, this line was the very first synthetic fly line ever produced. Today, anglers still trust Cortland first top quality, dependable, performance fly lines. The 333 Classic has been re-engineered for today's modern action fly rods and features a longer belly to load rods more quickly and carry more line in the air for improved distance. Durability and satin smooth finish are second to none.
