This face mask is great for casual, business, or dressy attire. The mask interior features two layers of breathable fabric and a pocket for an optional filter. It is made to protect from the top of the nose to the bottom of the chin. The soft elastic ear straps easily adjust by sliding the rubber pieces to a comfortable fit. One size fits most. These masks are for general non-medical purposes only. We believe medical, surgical, or N95 masks should be reserved for healthcare workers and medical first responders.
