Best 4wt Fly Line | Montana Casting Co.

Our 4wt fly line is the perfect choice for delicate presentations and technical fly fishing. A 4wt in any of our three fly line choices, MC-30, MC-38, and MC-40, is ideal for backpacking trips into the wilderness to fish streams and high mountain lakes. Designed to cast effortlessly and accurately, this line is ideal for targeting trout, bass, or panfish.

Do you need a weight-forward fly line for small streams? Or are you looking for a line with a classic cast for bigger waters? With 3 different line designs to choose from, we have a 4wt line that will work wherever your fly fishing trips take you. Looking for a different line weight? Check out our entire lineup of fly line. All of our precision-engineered fly lines are designed to deliver a smooth and accurate cast and have been rigorously tested on Montana waters by Montana Casting Co. and our crew of field testers.
