The Fischer RC4 Worldcup SL Curv is a powerful and precise FIS Legal slalom ski for men. Fischer's Hole Ski Technology reduces the amount of inertia that it takes to roll this burly ride between the gates. The Air Carbon Ti Construction has two Titanal layers that are reinforced with Air Carbon that will grip an icy course and keep you smooth when you are tearing down a course. The Concave Sidewalls make for easier tuning for you to put that perfect edge on your skis. The Worldcup SL has the World Cup Binding Plate that allows for a smooth flex pattern and can only accept the Fischer FreeFlex Binding System (Sold Separately). If you are the real deal and need to ski the real deal for sanctioned races, the Fischer RC4 Worldcup will be a perfect ride for you.
