About Madshus Hypersonic Ski: Next in our line up is the Hypersonic. In many ways this is or was similar to the Panasonic it does come in a skate version and a classic version. Up until 2 years ago this was our top end World Cup ski so we took this ski and this is now a second in our line the hypersonic. Beautiful ski for serious racer all the way up to training for very serious races.
