Two completely new technologies make the “In-Touch” series the must-have sinking fly line for all lake anglers. Each line is built with RIO’s new and unique non-stretch “ConnectCore”, which produces a fly line with virtually no stretch. When fishing with sinking lines, anglers rely on touch to know what’s going on in the depths, and when touch is so important, line stretch is the enemy. RIO’s new ConnectCore full-sinking lines open up new worlds of perception and sensitivity with no-stretch performance. Soft, subtle takes become positive grabs, and without line stretch to slow reaction times, hook sets are lightning-fast, instant and sure.
