摘要： A protective device comprising a mask part, which covers the wearer's mouth and nose and is provided with elements through which air can be supplied inside the mask part to enable breathing. To eliminate problems caused by draught, the mask part is provided with a wall portion, which is arranged to extend from the edge portion of the mask part against the wearer's face inside the mask part so that an interspace connected to the inner space of the mask part is formed between the wall portion and the inner surface of the mask part and that the elements through which air for breathing can be supplied inside the mask part are arranged to open into the interspace.
