I bought one navy and two baby blue masks. They are very nicely made but even though they're just one size, the navy one is bigger than the two others and I actually had to remove the baby blue one in the middle of the day as it became too tight behind my ears. I do also have to wear glasses, which of course puts even more strain on the ears. Just saying if you have a larger face and glasses, maybe try the behind the head ones instead. Ordering procedure and shipping are excellent.
Got the masks quickly and they do the job
Ear Loop Face Mask MADE IN USA - NAVY / WHITE
I love these. They are snug over the nose which I Like. I have two black ones and sometimes they are a little loose. Highly recommend.
