Partnering with our friends at Rio, we’ve taken their long-loved Outbound Short Fly Line and tweaked it just enough to make it a perfect fit for our specific needs. Starting with the line’s temp rating, we’ve kept the supple coldwater core that the OBS has used for years and added a hard tropical coating. This provides a wide range of versatility across fresh and saltwater, encompassing anything from colder days in the warm waters of Flordia’s canals to the cold spring tidal waters in our home state of Maine–and last but certainly not least, this line excels in situations when the air temperature is hot enough to heat a boat’s deck into the 80-degree range, yet the water is still a cool 60-degrees.
