Airflo can be credited for reinventing the fly line - for the sake of the environment!
For nearly 70 years, the majority of fly lines have been made from PVC - a naturally rigid plastic that requires the use of plasticizers to make PVC lines functional. These plasticizers are anything but a permanent part of a PVC line. From the minute it's made, a PVC line
begins breaking down - leaching plasticizers into the environment and contaminating you and the waters you fish. Once it has shed enough of these, it becomes prone to cracking, even failure. As it decomposes, PVC is known to release Dioxins - a group of lethal, bioaccumulating toxins. Consequently, it's virtually impossible to safely recycle a PVC line. All of which is why Airflo never uses PVC. Instead, their lines are made from Polyurethane - an inert, stable, fully recyclable material that requires no plasticizers and lasts far longer than PVC.
