8801 Pleated Face Masks are intended to decrease the spread of COVID-19 by reducing dispersion of bodily fluids when talking, coughing or sneezing. Face masks are made of two layers for soft, breathable protection that meets CDC and WHO recommendations. Exterior is 100 percent cotton twill, and interior is 100 percent polyester mesh for breathability. Internal mesh is treated with Microbial Z06 to kill odor-causing bacteria. Pleated design stretches vertically to securely fit over a range of face shapes and sizes. Nose clip adjusts to fit your nose and reduces fog when wearing eyewear. Elastic ear loops with adjustable sliders provide a comfortable, custom fit. Machine-wash and tumble dry masks for easy cleaning. Masks accommodate to fit a variety of head sizes.
