This unisex personal use Care Mask by WOLFORD is available in two sizes XS/S (Width 17 cm /Height 14 cm) and M/L (Width 20 cm/ Height 16 cm) to provide full coverage of the nose and mouth to different faces' size. The XS/S size is more suitable for petit women and children, while M/L is more indicated for full grownup men. Their double-layered high-quality fabric makes breathing easy while minimizing moisture buildup. The adaptable aluminum nose-wires ensure a snug fit at the nose, which reduces steaming upon glasses. Highly elastic, extra-thin bands fit gently around the ears to secure the mask in place. Our masks are also treated with special UV light before packaging to kill bacteria, viruses, and germs. Not only is this care mask reusable and washable for ease and sustainability, but washable at temperatures up to 60°C (140°F). Please note that this mask does not have a pocket to accommodate filters. Material: 91% polyester, 9% elastane.
