*New and improved design*

This premium adult face cover design has an added aluminum nose piece and hidden 1-way valve nestled  between 2 layers of 100% cotton fabric. The valve opens during exhalation. This helps to reduce heat buildup in the face cover. The exhaled air is filtered by a layer of cotton fabric. An additional layer of filtration can be added with a filter pad.  The adjustable nose piece helps minimalize fogging of classes. The nose piece also helps the mask "fit"your face better so it can put some relief on your ears.
