Designed for comfort and with a professional presentation, we now have a solution for singers and performers nationwide. The Singer's Mask was designed and manufactured by Broadway professionals. Based on feedback from their peers, this mask helps contain droplets while allowing space around the mouth to sing comfortably. The face mask area has three layers that includes a nonwoven Polyester, sandwiched by layers of cotton muslin. There are two small windows on both sides that don't have the Polyester middle, allowing for greater air flow. The top edge of the mask has a flexible wire inside (ear to ear) to custom fit your exact face shape and keep the material reliably away from the mouth. It's washable in cold water. In general, adult size is intended for high school and older. Youth is for 14 year-olds and younger. See face chart to determine. Made in the USA.
