ConnectCore Plus is RIO's next-generation, low-stretch core technology - providing a radical increase in line durability, smoothness and performance
Building a better fly line starts at the core, and our low-stretch ConnectCore Plus provides a radical increase in line durability, coating smoothness and overall performance. ConnectCore Plus gives anglers all the benefits of a low-stretch core—enhanced sensitivity, less wasted energy and faster hook sets—with a significantly longer lifespan.
The low amount of stretch also makes it very easy to straighten by hand in cold conditions - easily removing any memory coils for a more direct connection to fish and fly. The highest-performing, longest-lasting freshwater lines in the world are built around ConnectCore Plus.
