The RS-X series was created for advanced riders looking for the fastest foil with great carvability. It’s unmatched for its speed and maneuverability. The “RS” stands for Race Speed Series. These are the fastest wings in our collection. These wings are great for racing when Downwind Paddling or Winging. They are very fast, and turn and pump well. The RS wings are slightly thinner than the GT’s, which gives them the extra speed.
