New Airflo Sniper 4 Season Ridge 2.0 WF-10-S Sink7 #10 Weight Forward Fast Sinking Fly Line. All of which is why Airflo has never used PVC to produce our lines. Since 1984, our lines have been made from Polyurethane — an inert, stable, recyclable material that requires no plasticizers, performs better and lasts far longer than PVC lines.
