Air is a soft athletic mesh mask. This soft material is so much easier to breath all day and doesn’t get hot at all! Its light weighted plastic pullers can adjust the sizes, so everyone can and will fit in! Because the plastic is light weighted, you won’t even feel the weight behind your ears. You can adjust the wire and make it fit around your nose, people with glasses won’t have to worry about them fogging up. You can also insert extra PM 2.5 or 3M filter (not included) for extra protection.
