Reusable masks for teen?

[Eaudeunaturale]

Well preteen but size of a teen, starting secondary school in September and will have to catch a bus, needs something with a nose clip as the disposables we have need adjusting if he talks

I was going to suggest Gap, but they've sold out of adult sizes. My DS (also Y7 in September) wears the children's size...but he is weeny, about the size of larger 8yos.
Hype have some, which is v in with teens, but they are £££ (3 for £24!)

The problem I have is you can’t try them on so I don’t know what size he would be!
His face is almost the same size as mine and I reckon I’m about a Medium

Search on ebay and Etsy for teenage and small adult masks. There are lots of people selling face masks, it'll take a while to find them but some have elastic you can tie yourself which will help if the mask is a bit big/small. if it's not clear you can message a seller for size across face and from bridge of nose under just below chin.

Adidas do them. The Xs/S size is perfect for a teen. Think they were £12 for 3.
