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 being for experimental, this line was the very first synthetic fly line ever produced. Today, anglers still trust Cortland first for top quality, dependable, performance fly lines. The 333+ has been re-engineered for todays modern faster action fly rods and features a longer belly to load rods more quickly and carry more line in the air. Durability and satin smooth finish are second to none.
