This kid's mask is made with breathable fabric and provides coverage from the top of the nose to the bottom of the chin. The straps are made with ultra-soft elastic for extra comfort, and each end has rubber pieces that slide to adjust the straps to fit. This mask also comes with a built-in pocket to insert a filter if desired. One size fits most. Also fits most adults. These masks are for general non-medical purposes only.
