FAQ

Cleaning your fly line is very important especially when fishing saltwater. Simply pull line off your reel into a clean bucket or tub of freshwater. Put roughly 1oz or more of Cortland’s Line Cleaner solution onto a clean rag or towel. Firmly squeeze the towel with Pro Line Cleaner around the line and slowly pull line through the towel. You should be able to see dirt or discolored streaks on the towel when finished.

444 SL WF5F

Excellent fly line for old school two-piece and current generation graphite rods at an honest price. Great taper for both progressive-moderate and fast action rods. Courtland fly lines are an American icon. And no, I'm not sponsored by them. Just a person who was blessed to have started this sport after College in the early 80's ( "the golden age of flyfishing" ) and am now retired. You cannot go wrong with the 444 (peach) and 444 SL (bright green) fly lines. Highly recommend.

444 SL Fly Line – Precision Casting with Distance-Mending Control

July 15th, 2025

The Cortland 444 SL Fly Line has been a go-to favorite among serious freshwater anglers for over four decades—and with good reason. Designed for those who demand distance without compromising on presentation, the 444 SL combines a long, level head with high-visibility color and a slick coating that glides through guides with minimal resistance. Whether you're casting dries across a wide tailwater, swinging soft hackles through a long run, or mending line upstream to extend your drift, this line puts total control in your hands—even at range.

What sets the 444 SL apart is its extended body length and balanced taper. The line features a 41-foot head that delivers stable loops and enhanced mending ability, especially on bigger rivers or in windy conditions. While many weight-forward lines are built for power alone, the 444 SL finds the sweet spot between strength and finesse. The mint green color isn’t just easy on the eyes—it helps you track your line in shifting light or fast-moving water. Combined with a front welded loop for quick leader changes and a durable slick coating that resists friction, this line is built to perform cast after cast.

Built for Anglers Who Fish Beyond the Standard Reach

Not every trout stream calls for short, delicate casts. When your day demands precision at a distance, the 444 SL delivers. The long belly design gives casters better line control and smoother energy transfer over greater lengths, making it easier to mend upstream, extend your drift, or set the hook without slack. If you're fishing in faster water or targeting risers far across the river, you'll appreciate how this line handles the challenge without overpowering your presentation.

The reduced-friction coating keeps your casts smooth and your loops tight, even when shooting long lengths through guides. That means less fatigue over a long day of casting, and more accuracy when it counts. The line maintains its flexibility in cool to moderate climates, performing best in temperatures ranging from 30°F to 70°F. Its slightly heavier design helps load modern graphite rods more effectively, making it a solid choice for anglers who prefer faster-action equipment but still need precise loop control and long mends.

Classic Reliability with Modern Refinement

Despite its long-standing reputation, the 444 SL is far from outdated. Its design has quietly evolved to meet the needs of today’s freshwater fly fishers without losing the core qualities that made it iconic. It’s a favorite among guides and seasoned anglers alike because it just works—smoothly, consistently, and without surprises. There’s a certain confidence that comes with knowing how your line will behave, even in the most technical water or when you’re pushing the limits of your cast.

The 444 SL is particularly effective when fishing terrestrials, indicator rigs, or dry-dropper setups that require extra line management. The long head lets you pick up more line without losing control, while the high-floating profile keeps your fly in the zone longer. Whether you’re mending across seams, working long drifts from a drift boat, or targeting spooky trout from the bank, this line offers the reach and subtlety needed for success.

With its legacy of performance and a design tuned for today’s challenges, the Cortland 444 SL remains one of the most versatile and dependable trout lines available. It’s not flashy—but when you're 50 feet out and your fly lands just right, you'll understand why it’s stayed in anglers’ arsenals for over 40 years.
