Fly line selection isn’t just a technical detail—it’s the foundation of successful fly fishing. The right fly line allows you to present flies accurately, cast efficiently, and connect better with your target species. Whether you're stalking trout in a backcountry stream or chasing redfish on the flats, your line choice can make or break the day.
A pioneer in modern fly line technology, Scientific Anglers is renowned for its advanced coatings, slickness additives, and versatile tapers. Their Amplitude series is especially popular among pros for its durability and superior casting distance.
RIO combines performance and innovation with a wide variety of specialty tapers tailored for specific species and environments. Their fly lines are trusted by anglers worldwide for precision and control.
With a rich history dating back over 100 years, Cortland is a favorite among traditionalists and modern anglers alike. They offer dependable lines with consistent tapers and excellent sink-tip options.
Known for their high-quality fly rods and reels, Orvis also offers excellent fly lines engineered for smooth casting and consistent turnover. Their Hydros series delivers high performance for a range of fishing styles.
Fly lines come in weights ranging from 1 to 14+. The line weight must match the rod weight for optimal casting performance.
Fly line weight plays a crucial role in determining how your rod loads, how far you can cast, and what size flies you can effectively present. Choosing the right line weight ensures your setup is balanced and optimized for your target species and fishing conditions.
Fly line weights are measured on a scale from 1 to 14, with 1 being the lightest and 14 the heaviest. The line weight should match your rod and reel for smooth casting and proper energy transfer.
Fly fishing lines are designed to match specific environments—what works in a quiet mountain stream may fail in the heat and salinity of an ocean flat. Knowing the difference between freshwater and saltwater fly lines helps you choose the right gear for optimal performance and durability.
These fly lines are designed for colder, softer environments. Freshwater fly lines are built with more flexibility and lower stiffness to perform well in moderate to cold temperatures.

These are engineered for harsh conditions. Saltwater lines are stiffer and more rugged to withstand heat, UV exposure, and salt corrosion.

What’s the best fly line for beginners?
A weight-forward floating line in 5-weight is typically the most versatile and beginner-friendly option, ideal for learning in freshwater environments.
What is the difference between floating and sinking fly lines?
Floating lines stay on the surface, making them great for dry flies and topwater techniques. Sinking lines descend into the water column, which is useful for deeper fish or faster currents.
Can I use freshwater fly lines in salt water?
It's not recommended. Saltwater lines are built with tougher coatings and cores to withstand UV, salt, and larger fish. Freshwater lines may degrade quickly in saltwater.
