By using a soft, lightweight silver ion antibacterial fabric, the Courtesy Mask bay PKG is a comfortable face covering, allowing for easy breathability and style. The dense, soft touch knit binding around the exterior allows for stretch and a contoured fit with adjustable elastic ear bands for universal sizing. The antibacterial effectiveness remains 99% effective after 50 washes and can withstand temperatures upto 140 degrees Fahrenheit or 60 degrees Celsius in a machine wash and dry. The main feature of the Courtesy mask is to control dust, smoke and air particles, but should never be used as a protective medical device.
