The mask reinforces the sense of utility of “social distancing”. It adapts perfectly to the mouth and nose, adhering perfectly to the edges. The knitting technology makes it breathable and particularly effective even in outdoor sports activities in all environmental conditions. Thanks to the materials used, it is moisture repellent and dries quickly. It is important to wash the mask regularly at 60 C to eliminate pathogens. The mask is to be used for personal use only. It lasts long and is reusable. The mask reduces the risk of infecting other people. It is not a medical device.
