This toddler's mask is perfect for keeping them protected. It has ultra-soft elastic straps with rubber tubes that slide to adjust the mask to the perfect fit. The body of the mask is sewn to curve over the top of the nose and under the chin for full coverage. 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.
