Passion for brushes and outdoor activity

Thanks to its innovative nature and its passion, SIT has patented technologies and products in sports industry (ski but also golf and tennis). In 1962 Pietro Acquaderni created, starting from his passion for winter sports, and patented artificial ski slopes “QUATTROSTAGIONI”, that reproduce the attributes of snow, for downhill, jump and cross-country skiing.
Experience and intuitions lead to many patents and soon SIT became first inventor and manufacturer worldwide for brush ski slopes. Other manufacturers have eventually obtained the licenses to replicate our patented system in their countries.
