Designed specifically for chasing near-shore/inshore species

Designed specifically for chasing near-shore/inshore species, this line remains flexible and manageable even on the coldest of days. Its moderate front taper is the perfect blend of power and presentation. Ridge Tech coating, low-stretch Power Core and looped both ends. Available in floating and intermediate.

Suberp performance and strike detection

This .60mm line combines suppleness with incredibly low stretch for superb performance and strike detection. And its hi-viz orange tip ensures you'll see those strikes every bit as much as feel them. Micro loops at both ends provide easy, low-profile connections. 100% FIPS compliant.

Designed to straighten out heavy flies and large indicators

A good Nymph and Indicator line needs to be able to form efficient loops that can straighten out heavy flies and large indicators. Keely's new line has a larger tip diameter and more aggressive front taper to handle even the heaviest junk.

Even with a good cast, many struggle mending the line and controlling the drift. But, the Super-DRI Nymph/Indicator has an extended rear taper and a high floating front section to help mend and manage the line better than any we have ever made.

With our original low stretch power core you'll be able to stick fish at distance and with our Ridged surface, the line won't slip out of your hand while doing so.

Ideal for throwing big flies or hucking junk.

 Quickly loads at short range. Large tip diameter turns over big flies. Longer rear taper provides multiple pick up points. Haul zone extends the usable head length.

With an aggressive rear taper, and forward-biased concentration of mass the Superflo Power Taper is designed to be anything but subtle. Even it's coloration packs a punch.

All-round trout taper

This is the best all-round trout taper; the go-to trout line if you want to cover all types of trout fishing. Good for all casting styles and skill levels.

If you want to cast further with less effort, the SUPERFLO fly lines will significantly improve your performance out on the water.

Turns over any big fly or rig on even the fastest of rods

The Power Taper does exactly what it says - puts the energy in the line to turn over any big fly or rig on even the fastest of rods.

The addition of the Ridge 2.0 Tech makes it even easier to cast these heavy loads, and with less resistance in the guides, casts are going to go even farther than before.

The go to all-rounder fly line

The Superflo Universal Taper has quickly become the go to all-rounder fly line, performing flawlessly on every rod that anglers have put it on.

Now, its performance has been taken to the next level with the introduction of Ridge 2.0 tech: Faster shooting, increased line speed and a quiet line texture.

One of the most popular designs by Lee Wulff

Of the many innovations that Lee Wulff has contributed to fly fishing, the Triangle Taper fly line is perhaps the most popular. Winner of the coveted Kudo award, the triangle taper offers the greatest delicacy of any fly line. The Triangle Taper is a continuous forward taper in the head of the line, the first 27 to 40 feet depending on the application. This provides the most efficient transfer of casting energy as it unrolls because the heavier line is constantly turning over lighter line. This design also gives you a more delicate presentation because the weight is away from the fly. It is also the finest roll casting line for up to 60' casts. The combination of a long weighted section and a light running line make the triangle taper cast like a shooting head for distance. The tip end can be customized by cutting it back for the desired performance level.

The fly line that gives you easy-casting performance for both overhead and close-in roll casting. Renowned for its revolutionary taper design, which promotes efficient energy transfer. You'll enjoy more delicate presentations in any situation. Available in floating, 90' length with a 36'-40' taper and a 54'-50' running line with welded loop for easy leader attachment.

Winston Energy Fly Lines. A True Advancement.

Winston ENERGY fly lines were designed utilizing an entirely new scientific approach that enhances the energy transfer between the rod and line. By measuring the dynamic characteristics of fly rods at various flex points, we've applied an engineered system to precisely design lines that are ideal for each rod weight. The result is a series of lines that perfectly match the performance characteristics of today's fly rods, cast and fish wonderfully, and provide anglers with optimized line control, accuracy and, most importantly, presentation.
