After almost a year of extensive testing in a wide variety of environments, Endura Fly Line dressing is now available for purchase. Endura is being introduced by Walt Geryk, a member of Hardy/Grey's and Airflo's pro staff and a well known guide on the waters of New York's Salmon River. Endura is comprised of proprietary formula and is touted to offer line-changing performance in salt and fresh water and regardless of water temperature.
According to Geryk, Endura has been tested in conditions "ranging from freezing temps and 33 degree water to hot summer days on the Salmon River [and] the Miramichi, the Deerfield River region and into the salt waters of Cape Cod. Tested by dozens of anglers, [the] results are: lasts longer, applies on wet and dry lines, floats lines higher, slides through the guides with unnoticeable friction, increases casting distances and can be used on any fly or spey line. Gives older lines a like new slickness and floatability."
