The removable chin strap makes the helmet particularly versatile. "Rupicapra rupicapra" means 'chamois' in German. They are even faster downhill. With the Rupi, ambitious kids may not be as sure-footed as chamois, but they are much better protected. The Ceramic Shell in combination with the Hi-EPS core ensures that forces can be absorbed in the event of a fall. As good ventilation is also important when skiing downhill, the Rupi has 15 ventilation openings.
