4D InTouch Big Nasty Sink Tip

When you want to get your rig far out into the water and watch it drop just a few feet below the surface, the RIO 4D InTouch Big Nasty Sink Tip is the line you need. Its powerful, weight-forward taper loads your rod and easily turns over large flies even in windy conditions. The ConnectCore resists stretching and has very little memory, so it responds to the slightest movements immediately. Multi-Density Control technology uses three different density coatings to provide excellent depth control to the angler, while Extreme Slickness minimizes friction to ensure the line flows through the guides smoothly.


  • Sinking tip line for large flies and rigs

  • Multi-density control for maximum performance
  • Extreme Slickness minimizes friction for smooth flow
