Here's a better look at the Old Navy exclusive Sonic kid's face masks.
As the pandemic sort of winds down in summer of 2021, you can find this set of 3 soft cloth masks for about 12 dollars or so in stores. They're packaged in a clear plastic sleeve with the cardboard hang-top seen here. What's unfortunate of them, is that this packaging method HIDES the most attractive of the masks, which is the 'logo / title screen' mask. It is always sandwiched between the other 2, even though it is the most eye-catching / colorful one. The cardboard topper does not have a picture to show you what you get, you have to just guess that the 3rd mask is something good.
12 is a tad steep for kiddie sized masks if there's only 3. If you are an adult or a teen but have a fairly small head or low-set ears you should be able to wear them anyway but they are notably smaller than other masks. The fabric is really soft and the straps are stretchy, though. It is a comfortable set, and an interesting thing to have to mark having gone through the pandemic of 2020 specifically with something Sonic. These are in the SonicGear collection
