This face mask and headband set is great for relieving any tension behind your ears from face mask ear straps. The buttons on the sides of the headband can be used to loop the ear straps around them. The mask has an interior pocket for an optional filter, in addition to, a sewn in filter on the exterior. The mask is made to cup over the nose, mouth, and chin for full coverage and has a flexible wire sewn into the bridge of the nose for a better fit. The elastic straps have a rubber tube that moves to adjust to the necessary size for 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.
