The Sporten IRIDIUM 5 W + VSP 311 are lightweight sandwich skis with sports ambitions. The skis features a lightweight core made from exotic wood, which works perfectly for a sports-level ride but are not limiting in terms of flex or weight. Just like other skis from the Performance line, the IRIDIUM also offers double radius for a confident, smooth turn transition. An interesting feature is the option to move the binding to use the double radius for short and medium turns.
