The Baron Junior is the kids’ version of Baron so in a reusable and recyclable pack (cardboard box instead of the reusable bag) and a more simplified aesthetics, but with identical features that differentiate it from other face masks on the market. The Baron project has required in-depth studies of the design and circulation of both inlet and exhaust air, in order to solve the usual problems in these masks in competing models and make the Cressi face mask especially safe in any situation. The valveless design guarantees a large supply flow, unthinkable in other similar models, especially in case of fatigue or stress. The evacuation of the exhalation is channeled in separated ductwork that prevents the accumulation of carbon monoxide in the breathing zone. The air circulation in Baron is clearly superior to that of any other mask on the market. Tested in the laboratory of the Engineering Department of the Milan Polytechnic, where the results exceeded any expectations.
