Power Taper
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. Ultra-thin running line shoots like hell and takes up less spool space. 
 
Ridge Tech 2.0
Ridge 2.0 takes textured fly lines to the next level. The all-new ridge profile decreases friction in the rod guides, generates higher line speeds, and minimizes tangling - yet feels and sounds like a smiith line. All the benefits of textured lines and non of the downsides. Why not have it all? 
 
PVC Free
Unlike most of the industry's PVC lines, Airflo lines are made of polyurethane, an inert, flexible material that won't dry out or crack. Polyurethane makes for much more durable fly lines with far stronger welded loops. It also doesn't break down in UV rays, bug spray, or sunscreen. At the end of the season, Airflo lines perform like new. Airflo fly lines aren't just better for fishing, they;re also much better for the environment than their PVC counterparts. But don't take our word for it, look it up.
