Not adjustable but fit just right for me (woman with a large head!)
I appreciated the value and how light weight these masks are. I have to wear masks outside and in a barn when doing farm work with others and this gives me protection but doesn't cause me to sweat compared to my other masks. Be mindful that these are non-adjustable so would probably be most appropriate for men or women with bigger heads like me. (FYI, I need special x-large hats/helmets!)
