This face mask is designed so you can adjust a perfect fit just for you! Fine-tune the mask to hug your face and protect your nose and mouth from the inhalation of dust, pollen, spray, and other fine particles in the air. These masks are comfortable and very soft with 2 layers of fabric, and the ear loops contain no elastic. The masks also have an innovative neck strap, so that you can hang the mask from your neck when not wearing it on your face, freeing up your hands and pockets for other things. Leave this mask on around your neck all day! The masks are washable and reusable. The masks also have an air filter pocket to put in your preferred air filter for extra protection. Made in USA. AIR FILTERS NOT INCLUDED.
