This mask fits perfectly. You can choose to cover your ears with the ear muffs, or leave them hanging if you don't want them on at the moment. Personally,. I like to leave them on because they help cancel out the noise around you, which is especially helpful if you are wearing headphones (like airpods) or trying to sleep. The mouth hole seals up seamlessly, and is super convenient to take a sip or quick bite to eat without removing the mask. The design is simple and comfortable. It might not fully protect against the coronavirus, but it definitely suits my everyday needs.
