Special purchase: This pattern may not be re-orderable. Very breathable and easy to wear. These washable and reusable masks are not rated for medical use, but they are great to have on hand as extras in your office, car, entryway etc. for any time that someone forgets their mask. As we discovered in Washington state, when we had precautionary COVID requirements and smoke from western fires at the same time, they're also useful for general environmental contaminants including smog, dust and pollen, so hold onto them after the pandemic is over. Large size fits most. The 3mm elastic band is durable and comfortable, with a latex inner core and fabric outer layer. Made in Mexico of USA and Mexico materials.
