There is a tectonic upward shift in floating lines at Airflo that makes lines float higher for better presentations, easier mending, and smoother pickups. Airflo Superflo Max lines are still made from inert polyurethane, but what now makes them float is completely different. One of the many benefits of these polyurethane fly lines is that you can pack more tungsten into less coating and produce a line that is narrower and more dense. That’s why Airflo sinking lines have always been the answer when you want to go deep, fast. To create floating lines, however, Airflo has historically used gassing agents to blow air bubbles into the coating to decrease density. The inconsistency of this process sometimes resulted in lines that didn’t float consistently.

The solution? The new Superflo Max floating lines coming in 2025 use glass spheres for flotation, but it took more than four years of research and development to perfect the process. Because polyurethane lines are extruded under very high pressure and then cooled, the glass spheres have to be tougher than similar spheres used in PVC lines, and the result is a line that is super durable.

To ensure consistency in the mix, a team of new engineers has developed new production and extrusion equipment with advanced measuring systems to ensure quality and constantly check the surface for imperfections, measure grains by inch, diameter, and taper to confirm the best possible flotation and performance.

We used prototypes of the new Superflo Max Ridge 2.0 Universal line the summer of 2024 and found the lines floated much better than any previous Airflo line we’ve ever used. And they continued floating after weeks of use. The lines also have zero memory in normal trout temperatures, and very little stretch. There’s no need to stretch this line anyways, because it doesn’t come off the reel with coils. Because the polyurethane is inert and doesn’t degrade or leach off softeners or lubricants, the line is very durable and stays “like new” for much longer. According to Airflo, the glass spheres make the line even more durable because they cannot be crushed, pinched, or damaged.

The lines come on solid, reusable two-piece plastic spools that are made from 100% recycled material and can be recycled. You can save it for when you need to switch lines or store the line, or you can recycle it along with the fly line using the Airflo Zero Waste Recycle Program. Look for a Zero Waste Recycling Box at your local fly shop.
