During this Covid-19 emergency period we stopped our normal production and concentrated on modifying the Decathlon snorkeling masks with the technical drawings of the valves made so far in Brescia. Our £ d printers are producing both the version of the fittings for the sick and the version for the sanitary that allows the installation of FFP3 filters. We think it is right to give our contribution, in our own small way, with the precision and passion that has always distinguished us in our work. We will donate these aids to hospitals.
